China rebukes U.S. deterrence talks with South Korea, Japan

June 18 (Asia Today) -- China expressed strong opposition Thursday to recent U.S. extended deterrence talks with South Korea and Japan, warning that expanded nuclear cooperation could increase the risks of nuclear proliferation and conflict.

Chinese Foreign Ministry spokesman Lin Jian said Beijing was "deeply concerned" about efforts by the United States and Japan to strengthen extended deterrence.

Lin was responding at a regular news briefing to a question about the Japan-U.S. Extended Deterrence Dialogue and the sixth meeting of the U.S.-South Korea Nuclear Consultative Group. Japan and the United States held their talks in Tokyo from June 8 to 9, while Seoul and Washington held their meeting in South Korea.

"Extended deterrence is a product of the Cold War," Lin said. "Certain countries have strengthened nuclear deterrence cooperation for geopolitical purposes, increasing the risks of nuclear proliferation and nuclear conflict."

Lin said many countries had expressed serious concern and strong opposition to extended deterrence arrangements during review conferences for the Nuclear Non-Proliferation Treaty.

He reserved his strongest criticism for Japan, which has recently been embroiled in heightened tensions with China.

"Japan has long advocated building a world without nuclear weapons, but in reality, it has continued to increase its dependence on the so-called nuclear umbrella," Lin said.

He accused Japanese officials of making "dangerous remarks" about potentially acquiring nuclear weapons, saying such discussions pose a serious challenge to the post-World War II international order and the global nuclear nonproliferation system.

Lin urged Japan to reflect on its conduct, fulfill its obligations under the Nuclear Non-Proliferation Treaty, abide by its three non-nuclear principles and refrain from seeking nuclear weapons in any form.

His warnings to the United States and South Korea were less severe.

Lin urged Washington to abandon its "Cold War mentality," stop what he described as provocative policies and abolish nuclear-sharing and extended deterrence arrangements.

He said the United States should take concrete action to protect regional peace and security and maintain global strategic stability.

Addressing South Korea, Lin said Beijing hoped Seoul would "act cautiously and do more things that contribute to regional stability."

During the same briefing, Lin also criticized plans by Group of Seven leaders to reduce their dependence on China for rare earth elements and other critical minerals.

He urged the group to follow market economy principles and international trade rules and to stop using the rules of "small groups" to undermine the international economic and trade order.

China has said its export control system is consistent with international practices and intended to protect regional stability and meet its nonproliferation obligations.
