TOKYO (BLOOMBERG) - Japan is seeking to conclude months of talks on a broad post-Brexit trade deal with Britain later on Friday (Sept 11) when top negotiators speak via a video conference.

Japanese Foreign Minister Toshimitsu Motegi, who has led Tokyo's team on the pact, told reporters in Tokyo he will be speaking with British Trade Secretary Liz Truss on the agreement.

Japan's existing accord with the European Union, which includes Britain, runs until the end of the year.

Britain expects the deal to increase trade with Japan by about £15 billion (S$26 billion) a year in the long term.

Trade between Britain and Japan was valued at more than £39 billion last year, and Japan is Britain's 11th-largest export market.

Mr Motegi said earlier this month that Japan is seeking to reach the agreement before Prime Minister Shinzo Abe steps down, which is expected to take place next Wednesday.

Mr Abe said he's leaving office for health reasons.
