It appears the US wants back in the Comprehensive and Progressive Trans-Pacific Partnership (CPTPP).
President Donald Trump has reportedly told top trade officials to do what they can to get the US back on board, "on our terms of course", reports The Washington Post.
Quitting the CPTPP, or the TPP as it was then known, was one of the first things Mr Trump did when he became US President early last year.

His change of mind appears to have come after a meeting with lawmakers and governors. Senator John Thune, a Republican from South Dakota, said they told the President the best way to counter China's growing influence in the Pacific region was trade.
"If you really want to get China's attention, one way to do it is start doing business with all the people they're doing business with in the region: their competitors," Mr Thune told the paper.
Mr Trump said to "take a look at getting us back into that agreement, on our terms of course", Mr Thune said.
"He was very - I would say - bullish about that."

Mr Trump recently started a trade war with China by increasing tariffs on goods from the rapidly growing country.
The CPTPP was signed earlier this year by 11 countries - New Zealand, Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, Peru, Singapore and Vietnam.
Several US-friendly provisions from earlier versions of the agreement were suspended when the US withdrew, but not completely dropped.
Mr Trump first indicated in January he may move to bring the US back to the table.
