“The Trump administration would have had a strong hand if it had insisted on renegotiating TPP when the president took office in January 2017,” Alden said. “The US position is much weaker now.”

A number of provisions covering issues like intellectual property that the US government successfully pushed into the original deal were suspended in the new TPP signed last month. Bringing them back would require the agreement of all 11 signatories.

The other TPP countries might be willing to do that in exchange for greater access to the US market, said Deborah Elms, executive director of the Asian Trade Centre in Singapore. But if the Trump administration starts asking for further changes, that would make it harder to swallow.
