The U.S. has also raised concern about analyst reports based on satellite imagery that China is building missile silos in its northwestern desert and its test of a hypersonic missile last summer.
“On the assertions made by U.S. officials that China is expanding dramatically its nuclear capabilities, first, let me say that this is untrue,” he said at a briefing in Beijing.
The briefing was held a day after China, the U.S., Russia, Great Britain and France issued a joint statement on preventing nuclear war or an arms race. The statement was supposed to be timed to the start of a global conference on disarmament at the U.N., but the meeting has been postponed because of a surge in COVID-19 cases.
The U.S. Defense Department said in a report in November that China is expanding its nuclear force faster than previously predicted and could have more than 1,000 warheads by 2030. The U.S. has 3,750 nuclear weapons.
