Japan and the United States will hold a fresh round of talks Monday in Tokyo to bridge gaps over the Trans-Pacific Partnership trade pact that remain after the latest ministerial talks in Washington, a government official said.

Japanese and U.S. trade officials involved in the Pacific Rim free trade initiative will hold what could be the last round of talks before a summit on Thursday between Prime Minister Shinzo Abe and President Barack Obama in Tokyo, hoping for a breakthrough in the market access impasse, the government official said Friday.

"We still have big differences," Akira Amari, minister in charge of the TPP issue, told reporters after wrapping up a three-day ministerial meeting with Michael Froman, U.S. trade representative, through Friday morning.
