Tension over the South China Sea highlights the need for the United States to maintain a strong Navy to serve as a deterrent, U.S. House Speaker Paul Ryan said on Thursday, criticizing the Obama administration for proposals he said would reduce the U.S. naval fleet.

"This just shows that we need to have a strong navy," Ryan said at a news briefing. "We should not have a president proposing to lower our ship count to pre-World War I levels. This means we need to have a strong military and a strong Navy, and a real foreign policy, which we do not now have."

Ryan's comments came one day after China again landed a plane on a disputed island in the South China Sea. In addition to China, Vietnam, Malaysia, Brunei, the Philippines and Taiwan have rival claims to territory in those waters.
