The four straits of Malacca, Sunda, Lombok and Ombai Wetar are used by China’s People’s Liberation Army (Navy), or PLA(N), to cross between their bases in the South China Sea and the Indian Ocean.
That leaves the PLA(N) with three warships in the vicinity -- its routine deployment in the Gulf of Aden for anti-piracy escort duties. In addition to this “28th Anti-Piracy Escort Force” (APEF), as the three-vessel task force is called, three more PLA(N) warships that had formed the 27th APEF are currently visiting African ports.
The Indian Navy, meanwhile, continues maintaining a heavy presence of battle-ready warships in the Arabian Sea, including many close to the Maldives.
