The president indicated that he was not happy with North Korea for its actions and China for its lack of help on the issue.
Donald Trump has accused North Korea of “behaving very badly” – and said that China has done “little to help”.
In a post on his Twitter account, the US president said: “North Korea is behaving very badly. They have been ‘playing’ the United States for years. China has done little to help!”
His words came as US Secretary of State Rex Tillerson said military action against North Korea was an “option on the table”.
The president’s highest-ranking diplomat said during a visit to South Korea that he would bring an end to the policy of “strategic patience”, where the US tolerated nuclear tests and missiles from the country.
Instead, he said, the US would explore a range of military options, alongside diplomatic, security and economic measures.
