Foreign Ministry said on Tuesday that the Japanese side is making a fuss by hyping a normal infrared camera equipped on an oil and gas field exploration platform in the East China Sea.

The remarks, made by the spokespeople's office of the ministry, came after Japanese media said that China is installing a surface-search radar on one of the exploration platforms and the Japanese government believes it could help China to improve its military capability in the East China Sea.

The related platforms are positioned within waters under its own jurisdiction, the office told China Daily.

According to the office, the facility that the Japanese side mentioned is a normal infrared camera on the platform, and its aim is to observe situation around the platform and ensure its security, it said.

"The Japanese side should not make a fuss over it," it added.
