China 'sends warning' with release of photographs of disputed South China Sea island
Photographs of Yongxing Island show lengthy runway that could be used by the military

China has released the first high-resolution photographs of a newly built runway on a disputed island in the South China Sea.
An analyst said the aim of publishing the photographs of the airstrip at Yongxing Island, or Woody Island, was to send a warning to Vietnam and the United States that China was strengthening its military presence in the area.
Beijing had also been angered by the United States announcement earlier this month that it was partially lifting its 40-year-old arms embargo on Vietnam, analysts said.
Yongxing, Sansha city's main island, is built on one of the Paracel Islands that are also claimed by Hanoi.
The photographs were published on the websites of Xinhua and other major Chinese news portals, including one showing large signs saying the airstrip had been built by military and civilian contractors.
Yongxing Island is 1.8km wide, but the airstrip is more than 2,000 metres long, suggesting to analysts that it could also be used by the military.
