Vietnam expanding South China Sea runway: U.S. think tank
WASHINGTON (Reuters) - Vietnam is extending a runway on an island it claims in the South China Sea in apparent response to China's building of military facilities on artificial islands in the region, a U.S. think tank reported on Thursday.
Satellite images taken this month showed Vietnam had lengthened its runway on Spratly Island from less than 2,500 feet (760 meters) to more than 3,300 feet (1 km), Washington's Asia Maritime Transparency Initiative said.
AMTI, a project of the Center for Strategic and International Studies think tank, said continued reclamation work would likely mean the runway was extended to more than 4,000 feet (1.2 km).
It said the upgraded runway would be able to accommodate maritime surveillance aircraft and transport planes, as well as combat aircraft.
