A Dutch warship was harassed by Chinese military aircraft in the East China Sea on Friday, the Netherlands said, becoming the latest country to accuse Beijing’s forces of initiating potentially unsafe encounters in international waters.

In a statement Friday, the Dutch Defense Ministry said two Chinese fighter jets circled the frigate HNLMS Tromp several times, while its marine patrol helicopter was “approached” by two Chinese warplanes and a helicopter during a patrol.

“This created a potentially unsafe situation,” the statement said.
