The Philippines said Friday it will strengthen its military facilities on islands and shoals in the disputed South China Sea and announced initial plans to build a new port and pave an existing rough airstrip.

Defense Minister Delfin Lorenzana had been scheduled to inspect an outpost on Thitu, one of the disputed Spratly Islands, but his trip was cancelled because of "safety issues" and he spent the day instead at a military base where he unveiled the development plans.

"We will build a runway and a port, a pier, for our ships" on Thitu, Lorenzana told troops at the Western Command's 41st anniversary. "We are a bit blind in that area."
