China Coast Guard ship damaged in humiliating collision with PLAN ship now under repair in Hainan

China Coast Guard ships routinely patrol Scarborough, which Beijing calls Huangyan Dao, as part of historic claim to much of the South China Sea. Sovereignty over the Scarborough Shoal has never been established.

A landmark 2016 ruling on the South China Sea by the Permanent Court of Arbitration in The Hague, which voided Beijing's sweeping claims to the region, was not tasked with establishing sovereignty.

But it ruled China's blockade of the shoal violated international law and said the area was a traditional fishing ground for several countries. China rejected the ruling.
