Tokyo, Japan (Reuters): An adviser to Prime Minister Shinzo Abe confirmed on Wednesday that Japan will tell the United States in their economic talks that any border tax the U.S. government imposes on imports should not break World Trade Organization rules .

Yasutoshi Nishimura, adviser to Prime Minister, also said that Japan would not rule out a bilateral trade agreement with the United States, but talks may not start soon because Washington is putting a higher priority on renegotiating the North America Free Trade Agreement.

Nishimura told Reuters in an interview, "We don't want any border tax to violate WTO rules by becoming a tax system intended to promote exports."

"Our position is WTO rules and multilateralism are important and we want to lobby for that."

Abe and U.S. President Donald Trump agreed last month to establish a new framework for economic dialogue to discuss trade and infrastructure investment. The two countries have not set a schedule for their talks.
