With U.S. President Donald Trump tapping into populist anger at globalization and withdrawing from the Trans-Pacific Partnership trade deal, Japan has been exploring ways to move the pact forward with the 10 remaining members.

Calling the TPP "a thing of the past" for the United States, Vice President Mike Pence signaled an eagerness to start negotiations on a bilateral free trade agreement with Japan, given Trump's preference to handle trade issues bilaterally to better reflect the interests of U.S. industry and workers.

The trade ministers of the now 11 TPP countries are planning to meet later this month in Vietnam in a test of their resolve to bring the high-standard agreement into force amid concerns about protectionist sentiment being fanned by Trump's "America First" policy and Britain's decision to exit the European Union.
