U.S. President Donald Trump is willing to start market liberalization talks with Japan and four other Trans-Pacific Partnership members that don't already have free trade deals with the United States, the Office of the U.S. Trade Representative said Wednesday.

Trump has "indicated a willingness to engage with the other TPP countries — either individually or collectively — on terms that will lead to significantly improved market outcomes," the USTR's annual report said.

"In 2018, the Trump administration will continue efforts to build stronger, better and fairer trading relationships with these countries," the report said in reference to Japan, Vietnam, Malaysia, New Zealand and Brunei.
