The US President said that he had a “very productive” phone call with Chinese President Xi Jinping as tensions grow between America and North Korea.
Kim Jong-un is reportedly ready to launch a nuclear weapons test as soon as Saturday, with satellite images showing that its Punggye-ri test site is “primed and ready”.
The news comes after Donald Trump warned that an “armada” is on its way to join the US Navy aircraft carrier that was deployed in the Korean peninsula earlier this week.
North Korea has promised to retaliate to the show of force with a “powerful show of arms”.
Mr Trump said: "We have a very big problem in North Korea. And, as I said, I really think that China is going to try very hard, and has already started.”
China and North Korea have been allies since the end of the Second World War, but the relationship has cooled since Kim Jong-un came to power in 2011.
Mr Xi is said to take a dim view of Kim’s leadership and nuclear weapons programme, and the two men have never met face-to-face – although Mr Xi has met his South Korean counterpart.
Nonetheless, China remains North Korea’s only major ally and a major supplier of its supplies. With diplomatic relations at a 70-year low, here is a look back at North Korea and China’s history.
