WASHINGTON: US President Donald Trump alleged on Sunday that nuclear-armed countries, including Russia and China have conducted underground nuclear tests unknown to the public.
"Russia's testing, and China's testing, but they don't talk about it," he said in an interview with CBS's "60 Minutes" program, when asked about his surprise order on Thursday for the United States to test nuclear weapons.
"You don't necessarily know where they're testing... They test way underground where people don't know exactly what's happening with the test," he added.
US President’s announcement signaling a possible resumption of US nuclear testing after more than three decades has drawn mixed reactions from nuclear policy experts.
Trump’s decision came after Russian President Vladimir Putin said that Moscow had successfully tested a nuclear-capable, nuclear-powered underwater drone, in defiance of Washington's warnings.
In response to the US president’s decision, the Iranian Foreign Minister Abbas Araghchi last week said that the US announcement was a threat to international peace.
Replying to Trump's claims about China, Foreign Ministry Spokeswoman Mao Ning denied testing any nuclear weapons.
"China has always adhered to the path of peaceful development, pursued a policy of no first use of nuclear weapons, upheld a self-defence nuclear strategy and abided by its commitment to suspend nuclear testing," she said in a press conference.
