China's People's Liberation Army opened one of its bases to foreign media to showcase an elite helicopter unit.

The rare military display came as Beijing announced the creation of its newest city, Sansha, on a remote island in the South China Sea, a region where tensions have been rising over territorial disputes with neighbouring countries.
