US President Donald Trump has lashed out at China for undermining its work with North Korea, as criticism over progress on denuclearisation mounts.
In a series of tweets he also said he saw no reason to resume the joint war games with South Korea that have angered North Korea.
Days ago his own defence secretary said military exercises might continue.
China has accused Mr Trump of “shifting blame” in his comments on its relations with North Korea.
A summit between Mr Trump and North Korean leader Kim Jong-un in June ended with a pledge from the North to work towards “the complete denuclearisation of the Korean peninsula”. Soon after Mr Trump announced there was “no longer a nuclear threat from North Korea”.
But since then many observers say North Korea is not moving fast enough to dismantle its nuclear or rocket sites.
