It is vital for the MFA (Ministry of Foreign Affairs) family to engage in collective reflection at critical inflection points, and we are certainly facing such a moment.

I believe Covid-19 has not fundamentally altered the course of history. But it has accelerated pre-existing trends that were already well under way. So our world will be profoundly different - and Covid-19 has been the catalyst.

Post-Covid-19, we will inhabit a more dangerous, divided and disrupted world.

Why? First, long-term transnational threats - these include climate change, terrorism, cyber attacks, nuclear proliferation - all retain their potency.

And Covid-19 may not even have been the "big one". There have been other pandemics in human history with far higher mortality rates.

We may see another with greater potency. And bio-terrorists will have noticed how effectively contagion has brought the world to a halt.

Second, Covid-19 has exacerbated fundamental problems with the global economy. These include the explosion of global debt; increasing inequality; the pushback against globalisation and free trade; and increasing the bifurcation of technology and supply chains.

In good times, just-in-time supply chains were considered to be the most efficient. But countries now, all over the world, will develop "just-in-case" supply chains for the sake of resilience.

When the world opens for business again, I think we will see shorter, more fragmented supply chains. If you think about it, this has obvious implications for hubs like Singapore.

The imposition of lockdowns has sped up our shift online, and in some cases, emphasised the disparities in digital access. It's worth remembering that "work from home" also means "work from any country", and this means there will be greater competition for everyone, everywhere.

Meanwhile, the fourth industrial revolution will continue to disrupt jobs, especially with the advent of AI (artificial intelligence) and robotics.

Third, superpower rivalry has sharpened.

The grave impact of Covid-19 and the calculus of domestic politics make it less likely that the United States and China will find room to accommodate one another.

We all hope that "hot" conflict will not erupt. But with less strategic trust and less interdependence, the risk of miscalculation has escalated.

Even without overt conflict, the world is likely to be less stable and less prosperous.

Everyone hopes that the US and China will find a way to work together.

The US is still the world's pre-eminent superpower. In economic, military and strategic terms, it is far ahead of us all. It is a dynamic and creative society, with great capacity for invention and innovation.

But truth be told, its domestic preoccupations and the long wars in Afghanistan and Iraq have left the US questioning the value of all its external engagements, including its longstanding alliances in Europe and Asia.

Furthermore, its declining relative share of the global economy has also led it, quite legitimately, to question its role in multilateral institutions like the United Nations (UN), the World Trade Organisation (WTO) and even the World Health Organisation (WHO).

This is a debate that has not yet been resolved in the American electorate.

Meanwhile, China is stepping up on the global stage. Beyond its growing economic might, it continues to develop its military and strategic reach.

China has also raised its profile at multilateral institutions, although its exercise of soft power has sometimes produced mixed results.

For now, US-China rivalry in trade, cyber security or technology will sharpen. And we can probably expect hard or harsh words from time to time, especially if they touch on sensitive domestic issues, or issues that China considers core interests, like Hong Kong or Taiwan.

Fourth, existing regional tensions can ignite quickly and unexpectedly. Over the past week - and mind you, this is less than three years since the crisis on the Doklam plateau - we learnt of the violent escalation along the Line of Actual Control in the Galwan Valley between India and China.

There have been incidents in our own region over territorial claims and maritime rights in the South China Sea.

HOW WILL SINGAPORE DO?

And so the question arises: How will Singapore survive and thrive in a post-Covid-19 world?

Let's start with some fundamentals. We will always be a tiny city state surrounded by larger neighbours. We straddle the Indian and Pacific oceans. We are a gateway into Asia and a hub, a safe space, for talent, ideas, finance, goods and services. We can never be completely self-sufficient. We import most of what we eat, drink, wear and consume.

Mr Lee Kuan Yew reminded us in 2009, and let me quote him - he said: "Singapore cannot take its relevance for granted. Singapore has to continually reconstruct itself and keep its relevance to the world and to create political and economic space. This is the economic imperative for Singapore."

So the point remains that finding relevance remains an existential imperative for us.

I believe that foreign policy begins at home. And Covid-19 has increased the urgency for us to achieve several simultaneous goals in the short term.

We have to keep the virus at bay. We have to cushion the immediate economic impact. We have to double down on economic restructuring and skills upgrading for our people, to prepare for jobs of the future. And we also need to strengthen our social compact.

On the foreign policy front, we have to continue to stand firm on our legitimate rights and uphold international law. We must also maintain our reputation for trustworthiness and reliability - especially in honouring the sanctity of contracts and never impounding materials in a state of panic.

And I would add that from time to time, we will have to say "no" to other states, big or small, far or near. We must do so in a way that makes it clear we are doing so in pursuit of our own enlightened, longstanding national interests; and we must never bow to intimidation or be tempted by inducements.

So, how should Singapore, and in particular, MFA, adapt to the new normal?

SERVING SINGAPOREANS

First, I emphasise we are here to serve Singapore and all Singaporeans.

In the last five months, all of us have received a deluge of phone calls, text messages, e-mails and appeals at all times of the day or night. We embarked on the largest consular operation in our history to bring Singaporeans home safe and sound. We fulfilled our pledge to leave no Singaporean behind.

Citizenship has its privileges. And when our citizens overseas wanted to return home to their families in a time of crisis, our MFA colleagues spared no effort in assisting our fellow Singaporeans in times of need, at all times of the day or night.

When countries imposed lockdowns, when universities closed, and when airlines began to cancel flights, we had to work with foreign governments, airlines and colleagues in other ministries to bring our Singaporeans home.

Closer to home, we organised transport to help the elderly, the sick, pregnant mothers, minors, and those with disabilities to return via our land links with Malaysia.

We had numerous complicated repatriations, for example, from Iran, Fiji, Mauritania, Slovenia and Peru, where we had to tap our friendships with countries like Malaysia, Japan, France, the United Kingdom, Mexico and Israel to help bring our people home.

Where possible, we reciprocated by offering available spaces on our own flights to our friends.

SUPPORTING MULTILATERALISM

The second thing we need to focus on: We need to support and strengthen the rules-based multilateral system.

A small state like Singapore will always need friends. Stable, reliable, trustworthy friends. In fact, if you think about it, small countries have no choice but to be globalised. And a small country needs a rules-based multilateral order, in which sovereign states interact as equals, and the voices of countries big and small are heard and taken into account.

This has been a consistent feature of our diplomacy, whether through the Forum of Small States with its 108 members, or the Global Governance Group. We continue to strengthen and form such coalitions to ensure multilateral dialogue remains open and inclusive.

Dealing with Covid-19 over the past few months has emphasised the importance of such networks.

In our immediate region, Asean came together early to ensure the smooth exchange of information and best practices. We worked with our partners like Australia, Canada, Chile, New Zealand and fellow Asean countries like Brunei and Myanmar to reaffirm the importance of sustaining supply chain connectivity, and we did the same at the UN in New York.

Minister Gan Kim Yong shared our experiences at the WHO, alongside other ministers.

All these activities ensured that Singapore remained active and heard, and participated in international health discussions at a critical time.

In times of crisis, Singapore must continue doing our part as a responsible global citizen.

Migrant workers have helped build Singapore, and when cases amongst them rose, we looked after them like our own.

When our neighbours and friends were in need, we donated masks, medical equipment, hand sanitiser and other essential supplies. We were similarly beneficiaries of such supplies when cases in Singapore rose.

So the point here is that we need to continue working with our friends to mutually support each other, and collectively strengthen multilateral structures and networks, whether it is the UN, the UN Convention on the Law of the Sea, the WHO or the WTO.

The alternative is a world where everyone acts only in their own interest, hurling accusations and putting up barriers, each scrambling to secure their share. It would be a world where the only law is the law of the jungle. This is not a road we want to go down.

STRENGTHENING RESILIENCE

Third: We will need to deepen our national resilience and advance our competitiveness in the new normal.

What that means for MFA and our partners is that we will need to continue to diversify sources abroad even as we seek to expand production at home.

Let me give you some examples. We are seeking out new partners for our food supply, whether it is rice from India, eggs from Ukraine, or frozen vegetables and chicken from Poland. We are also working with others like the Netherlands, Turkey and France.

In our neighbourhood, we had already stepped up our engagement with the Philippines, Thailand and Vietnam to boost agri-trade cooperation even before the pandemic, but the pandemic gave us an additional sense of urgency.

Planes have arrived from New Zealand carrying meat, seafood, eggs and fruit, and returned to New Zealand with medical supplies.

We will also continue to strengthen our relationships with key partners, to keep businesses going, to boost competitiveness. And in this, Singapore's reputation as a consistent and credible partner is a powerful asset.

When there was global panic and fear that countries would seize or prevent exports of essential supplies, our partners were confident that Singapore would not do so.

We have also maintained our role as a hub and as an air bridge for other countries seeking to repatriate their own people.

Singapore was a critical transit point between Latin America, Europe, Australia, New Zealand, and South and Central Asia.

Currently, we are negotiating Reciprocal Green Lanes to gradually open up channels for safe and essential travel. We launched our first partnership with China earlier this month, and we are in discussions with other partners.

We will continue to share research and support the exchange of knowledge across borders.

For example, China's scientists sequenced the Covid-19 genome in early January. The fact that they shared their research enabled our scientists at A*Star (Agency for Science, Technology and Research) to produce PCR (polymerase chain reaction) test kits early on.

Our health officials and scientists have collaborated with their counterparts in the US, UK and the European Union on epidemiology, testing, and developing treatments and vaccines.

While we continue to reskill our workers at home and develop our own digital capabilities, we also need to work across the whole of Government to maximise opportunities for Singapore and Singaporeans in the digital economy.

We have concluded pioneering digital economy agreements with partners like Australia, Chile and New Zealand. These will promote interoperability between digital systems and pave the way for Singapore's adjustment.

We will continue to strengthen the Asean Smart Cities Network that we established during our 2018 Asean chairmanship. The digital Asean initiative will reduce trade costs and support sustainable economic growth for all of us in the post-Covid-19 era.

At the UN, we work on issues like cyber security, building digital capacity and AI. Businesses, people and governments need to transact online safely and securely, and be able to interoperate with common standards and norms of responsible state behaviour in cyberspace.

That is another reason why we open-sourced the BlueTrace protocol to enable others to build their own tools on top of what we have developed.

MFA and the Smart Nation Office were able to work together to respond quickly to requests for information from many friends abroad, including Australia, New Zealand, Malaysia and Fiji.

THE FOREIGN SERVICE IN THE NEW NORMAL

Underpinning all of this, we need a flexible, resilient and responsive Foreign Service to carry Singapore forward in the new normal.

I want to emphasise this point: I am very proud of the men and women of the Foreign Service. They have gone above and beyond the call of duty; they have served our country with distinction, and our fellow citizens.

These last few months have not been easy for our MFA colleagues who have had to work under tremendous pressure and in the midst of the pandemic.

As we look forward, our success will depend on our identity, our values, our sense of duty and verve. And most of all, this is the embodiment of diplomacy by Singaporeans and for Singaporeans.
