The Philippines says it has delivered fresh supplies to a remote outpost it claims in the South China Sea.

Manila says Beijing’s attempts to “block, harass, and interfere with the supply mission” were unsuccessful.

Chinese ships fired water cannon at a Philippine supply mission to the Second Thomas Shoal in the disputed Spratly Islands two weeks before, stopping it from reaching the Filipino troops.

Manila enforces its claim using a decrepit navy ship with a few troops.

China’s embassy in Manila did not immediately reply to a request for comment.

Beijing claims almost the entire South China Sea, including the Spratlys, which is also claimed in part by the Philippines.

The sea is a rich fishing ground that is believed to hold vast oil and gas reserves.

Supply missions to the shoal have been a frequent source of friction between the two claimants.
