The Chinese Foreign Ministry said a unilateral US withdrawal would have a negative impact and urged the US to "think thrice before acting". On 23 October 2018, John R. Bolton, the US National Security Advisor, said on the Russian radio station Echo of Moscow that recent Chinese statements indicate that it wants Washington to stay in the treaty, while China itself is not bound by the treaty. On the same day, a report in "Politico" suggested that China was "the real target of the out". It was estimated that 90% of China's ground missile arsenal would be outlawed if China were a party to the treaty. Bolton said in an interview with Elena Chernenko from the Russian newspaper "Kommersant" on 22 October 2018: "we see China, Iran, North Korea all developing capabilities which would violate the treaty if they were parties to it. So the possibility that could have existed fifteen years ago to enlarge the treaty and make it universal today just simply was not practical."
