China and the US are running the risk of conflict, and should come up with a way to manage such crises as their warships engage in close encounters in the South China Sea, according to maritime strategy specialists. Collin Koh, a Research Fellow at Institute of Defence and Strategic Studies, said both sides should document such incidents to show what happened, including with photos and radar feeds. “[It is] definitely unprofessional if any warship tries to get this close. Though I wonder why the Chinese side even allowed that to happen,” Koh said.
