China has been accused of deploying an advanced surface-to-air missile system to the hotly contested Woody Island, in the South China Sea.
The allegation is supported by U.S. and Taiwanese officials – but Beijing says Western media is misportraying the issue.
This is a previous satellite image of Woody Island, called Yongxingdao by China.
The picture shows considerable building work – including a runway.
Woody Island is part of the Paracels chain, which has been under Chinese control for more than 40 years – but is also claimed by Taiwan and Vietnam.
Beijing says that it also owns the Spratly Islands and Scarborough Shoal, to the anger of the nearby Philippines, Vietnam, Malaysia and Brunei.
The red line indicates China’s claimed territorial waters.
