Malaysia has summoned China's ambassador to Kuala Lumpur to protest Beijing's maritime activities in its waters in the South China Sea.
Malaysian Foreign Ministry officials say the protest was against the presence of Chinese vessels in its exclusive economic zone near Borneo.
They say Malaysia's position is based on international law. Chinese survey ships were seen late last month in Malaysia's exclusive economic zone. But the officials didn't say if the protest was related to that case.
Malaysia also summoned the Chinese ambassador in June after 16 Chinese military planes were detected over its maritime zone. The incident prompted Malaysia to scramble fighter jets.
Beijing claims jurisdiction over most of the South China Sea. Its increasing presence has become a source of contention and vigilance with other countries that have competing claims in the disputed waters.
