President Donald Trump and Chinese leader Xi Jinping will likely speak this week, White House Press Secretary Karoline Leavitt said on Monday, days after Trump accused China of violating an agreement to roll back tariffs and trade restrictions.

Donald Trump has said he will visit China after speaking to its leader Xi Jinping over the phone. The US president said he had reciprocated with an invite to the White House during the "very good talk" - though such a trip has not been confirmed by either side.
