Defense ministry spokesman Yang Yujun said on Wednesday that China opposes any action that would harm national security of other countries and regional stability under the pretext of Pyongyang's missile threats.
Yang made the remarks at a monthly press briefing in response to the reports that Tokyo would set up a committee to deliberate the deployment of Terminal High Altitude Area Defense(THAAD) system in the country. And the blueprint is scheduled to be finalized before the summer.
Foreign ministry on Monday has also voiced China's position on the issue, urging Japan to "act prudently" and play a constructive role in maintaining regional peace and stability.
