History urges caution given that the Philippines grounded an old naval vessel on China's Ren'ai Reef in 1999 to reinforce its illegal territorial claim there.

1999年，菲律宾的坦克登陆舰“马德雷山”号冲上仁爱礁，并以“搁浅”“船身损坏需要修理”为名，开始长达25年的“坐滩”。

It also said the Philippines sent two vessels last week that intruded into the adjacent waters of Ren'ai Jiao and tried to deliver construction materials for the grounded military vessel.

菲律宾上周派出两艘船只侵入仁爱礁附近水域，并试图为搁浅的军舰运送建筑物料。
