A U.S. Navy carrier strike group sailed toward the Korean Peninsula late Saturday evening in a move that was widely interpreted as a warning to Pyongyang, just days after President Trump discussed the need to bring North Korea to heel with Chinese President Xi Jinping.

The USS Carl Vinson Carrier Strike Group was not scheduled to be in the Western Pacific but sailed there overnight instead of embarking on a series of planned port visits in Australia, the Navy said Saturday evening. The carrier, along with the destroyers USS Wayne E. Meyer, USS Michael Murphy, and the cruiser USS Lake Champlain, “will operate in the Western Pacific rather than executing previously planned port visits to Australia,” according to a statement from the U.S. Navy’s 3rd Fleet. The ship also brings Carrier Air Wing 2, which includes four squadrons of F/A-18 Super Hornets, along with helicopters, electronic attack and command-and-control aircraft.
