Q: The Asahi Shimbun carried a report which said that China was planning to establish an ADIZ over the South China Sea. On January 31, the Deputy Spokesperson of the US State Department made a statement on the related issue. And the Kyodo News reported that an official from the National Sucurity Council of the White House also touched upon the relevant issue in an interview with the news agency on January 30. What is China's comment?

答：中国作为主权国家完全有权根据自身面临的空中安全形势，采取包括划设防空识别区在内的任何措施，维护国家安全，任何人都不能说三道四。

A: As a sovereign state, China has all the rights to safeguard national security with any means, including establishing the ADIZ in response to the situation of air security. No one is allowed to make irreponsible remarks.
