China should be able to meet standards set out in a major trans-Pacific trade pact, trade experts say, forcing members to make a politically uncomfortable decision on whether to let Beijing join a deal created to counter its growing influence.

Britain joined the Comprehensive Progressive Trans-Pacific Partnership (CPTPP) at a meeting in Auckland last month just over two years after its application, clearing the way for members to consider others from China, Taiwan, Ukraine, Costa Rica, Uruguay and Ecuador.

China's application, by far the biggest economy, is next in line if they are dealt with in the order they were received, although that is not a given.
