BEIJING, March 8 (Xinhua) -- The development of China's national defense force, including naval forces, poses no threat to other nations, said Foreign Ministry spokesman Qin Gang on Thursday.

    Qin made the remarks at a regular press conference when asked to confirm reports that China might have its first aircraft carrier by 2010 and asked to comment on the necessity of owning an aircaft carrier and whether building an aircraft carrier would cause concern of neighboring countries.

    Qin said China's armed forces have a duty to protect the country's large coastal area and territorial seas.

    He said relevant departments will conscientiously study the aforementioned issues, taking into consideration of various factors.

    The national defense force operates to safeguard the nation's security and development interests, not to start an arms race with other countries, Qin said.

    Qin reiterated that China will adhere to a road of peaceful development and a defensive national defense policy. China is ready to work with the international community to build a harmonious world of sustained peace and common prosperity.
