And Sasse also said the deal has the added benefit of uniting countries against unfair Chinese trade practices.
An early test of the potential for the United States to rejoin could come as soon as next week, when Shinzo Abe, Japan's prime minister and an ardent champion of the pact, is to meet with Trump at his Mar-a-Lago resort in Palm Beach, Florida.
Trump tweeted that he "would only join TPP if the deal were substantially better" than the one negotiated by his predecessor, Barack Obama.
Republican lawmakers on the Capitol Hill praised the president's reconsideration of the trade agreement as China continues to target and increase tariffs on farm products from the center of the United States. Trump has warned that he could levy tariffs on $150 billion in Chinese goods, prompting Beijing to threaten retaliatory measures aimed at American soybeans, airplanes and other products.
The news drew a rebuke from opponents of the multilateral trade pact. With congressional elections later this year, he now faces pressure from some Republican lawmakers anxious that his protectionist policies could spiral into a trade war with China that would hit rural America.
A spokeswoman for Singapore's Ministry of Trade and Industry appeared similarly open to the USA rejoining, noting that the TPP was "designed to be an inclusive agreement, which is open to like-minded countries willing and able to meet its high standards".
As he often does, the President started to change gears after hearing complaints from important constituents - in this case, Republican lawmakers who said farmers and other businesses in their states would suffer from his trade approach because they send many of their products overseas. Bauerle-Danzman says the US would be at a disadvantage if it has to agree to new terms.
The barriers to a new pact are considerable. Several negotiation stakeholders told the New York Times that they'd be unwilling to bend to the us upon re-entry into the deal.
For its part, the Trump administration worries that the partnership will become a zero-tariff backdoor for Chinese goods into the USA market.
