Construction plan for island an 'issue within Chinese sovereignty'

China's reported construction plan on an island in the South China Sea is totally an issue within Chinese sovereignty, Foreign Ministry spokeswoman Hua Chunying said on Monday.

Hua made the comments in response to a report about China's reclamation plan on the island.

Observers said China's construction plan, if true, is primarily to improve people's living conditions there and its ability for humanitarian work.
