China firmly opposes certain individuals in the Philippines hyping up China-related issues and undermining bilateral ties, Chinese Foreign Ministry spokesperson Mao Ning said on Monday.

Mao made the remarks at a regular news briefing after the Foreign Ministry of the Philippines said on Monday that it has summoned the Chinese ambassador to the Philippines.

Developing and improving China-Philippines relations is in the interests of both countries, Mao said, urging the Philippine side to restrain certain politicians' irresponsible acts and words.
