The foreign ministry on Tuesday countered criticism from China over South Korea's extended deterrence cooperation with the United States and expressed hope that Beijing would play a constructive role in advancing the denuclearization of the Korean Peninsula and regional peace.

The response came after China's foreign ministry recently voiced concerns over extended deterrence cooperation between Seoul and Washington, as well as between the U.S. and Japan, and called on Seoul to act prudently.

"At a time when North Korea's illegal nuclear and missile programs continue to advance, maintaining a robust deterrence posture through extended deterrence cooperation between South Korea and the U.S. is a legitimate response aimed at protecting the lives and safety of our people, as well as a fundamental responsibility of any responsible government," foreign ministry spokesperson Park Il said at a press briefing.

Park stressed that such cooperation is fully consistent with the objectives and obligations of the Treaty on the Non-Proliferation of Nuclear Weapons, adding that South Korea continues to reaffirm its commitment to the international nonproliferation regime.
