China says it hopes this year will be a “landmark year” in relations with the United States, as the two sides prepare for an expected leaders’ summit later this month. On Sunday, Foreign Minister Wang Yi tells reporters in Beijing that the two leaders have had “good exchanges” at the highest levels. U.S. President Donald Trump is due in Beijing near the end of March. While China did not confirm the summit, Wang says both sides have a ready agenda for discussions. The U.S. and China have tensions over issues from trade to national security.
