BEIJING -- A Chinese defense spokesperson on Friday urged the Philippines to give up its "unrealistic illusions" and cease its "farces" in the South China Sea.

Zhang Xiaogang, a spokesperson for China's Ministry of National Defense, made the remarks in response to the recent illegal intrusion of Philippine vessels into waters adjacent to the islands and reefs of China's Nansha Islands, as well as a Philippine defense official's recent groundless claims about the Philippines' sovereignty over Huangyan Island and Nansha Islands.

"The facts are crystal clear, and the Philippines has no grounds to justify or deny its intrusions, provocations and wrongdoings," Zhang said.

The scope of the Philippine territory has been defined by a series of international treaties, and China's Huangyan Island and Nansha Islands are not within that scope, he noted.

The Philippines has deliberately distorted historical and legal facts to justify its infringements and provocations, he said.

He pledged that China will continue to take resolute measures to firmly safeguard its territorial sovereignty, as well as its maritime rights and interests.
