Chinese foreign minister Wang Yi said on Tuesday that those U.S. politicians who "play with fire" on the Taiwan issue will "come to no good end", according to a ministry statement.
He did not specify any U.S. politician. China has expressed opposition to a potential visit to Taiwan by U.S. House of Representatives Speaker Nancy Pelosi.
