China said it is "unreasonable and unrealistic" to expect it to enter trilateral nuclear-arms negotiations with the United States and Russia, arguing that the size and posture of its arsenal are fundamentally different from those of the two nuclear superpowers. Foreign-ministry spokesperson Guo Jiakun told reporters in Beijing that China maintains a strictly defensive nuclear strategy and will not take part in an arms race. Guo was responding to comments from U.S. President Donald Trump, who earlier this week said he had discussed arms control with Russian President Vladimir Putin and wanted Beijing involved. The Chinese official countered that countries with the largest stockpiles should shoulder primary responsibility for disarmament, while reiterating Beijing’s longstanding “no first use” doctrine. China’s government has previously resisted U.S. efforts to fold it into bilateral arms-control frameworks, noting that its warhead inventory is a fraction of those held by Washington and Moscow. Guo added that Beijing would continue to support global non-proliferation efforts but would do so on terms reflecting its “unique strategic security environment.”
