China is building a tsunami alert centre in the South China Sea, a media report said on Thursday.

The facility is being constructed in the South China Sea, Wang Hong, chief of the State Oceanic Administration, said on the sidelines of the closing ceremony of the annual legislative session on Wednesday, the Global Times reported.

"In fact, it has been begun operations and has already issued tsunami alerts to the international community, including neighbouring countries in the South China Sea," Wang noted, adding that the project has received UN approval.

This is the latest announcement on facilities China is constructing in the South China Sea, although Wang did not reveal the specific location.
