Malaysia will sign a contract to purchase Littoral Mission Ships from China when Prime Minister Najib Razak visits Beijing next week, according to a Facebook posting by the country's Ministry of Defense.

The text of a speech to be delivered by Malaysian Defense Minister Hishammuddin Hussein was posted on Facebook on Tuesday, but was later removed after Reuters asked a Defense Ministry spokesman for comment.

The purchase of the patrol vessels, if it proceeds, will be Malaysia's first significant defense deal with China and comes amid rising tensions in the South China Sea and as the United States and China compete for influence in the region.
