China plans to seek Japan's cooperation in tackling U.S. restrictions on steel imports at high-level economic talks in Tokyo on Monday, according to sources close to bilateral relations.

Earlier this month, Chinese diplomats told their Japanese counterparts that they wanted to put U.S. steel tariffs on the agenda for the talks and discuss what the two countries could do next together, the sources said Friday.

Japan is reluctant to get on the wrong side of the Trump administration due to the importance of maintaining the Japan-U.S. security alliance, they said.
