BEIJING - China's decision to set up a state security committee is aimed at improving systems and strategies to ensure national security, Foreign Ministry spokesman Qin Gang said Wednesday.

The Communist Party of China said in a Tuesday communique that the country is to set up the committee, but gave no further details.

"In general, all those forces who would tend to threaten or sabotage China's national security will feel nervous," said Qin at a regular press briefing..

Qin heckled a Japanese reporter who asked that whether China's decision is related to Japan's plan for a similar council.

"Your question placed a trap for me." Qin asked: "Are you trying to put Japan in that place?"

China and Japan are in territorial dispute over the East China Sea.
