"Of great importance to both of us is North Korea's pursuit of nuclear weapons, which threatens the security and stability of the region."
North Korea has fired a missile into the sea hours after the United States and China agreed to work together to prevent further missile tests from the state.
The surface-to-air missile was fired from a region close to the North’s eastern coast and flew around 62 miles, according to South Korea’s Yonhap news agency.
It’s the latest in a series of weapons tests carried out by Kim Jong-Un’s regime in an apparent response to military exercises between the U.S. and South Korea.
It comes after U.S. President Barack Obama said he was seeking to agree with Chinese President Xi Jinping on "how we can discourage action like nuclear missile tests that escalate tensions and violate international obligations".
The pair met on the sidelines of a nuclear summit in Washington yesterday.
At the start of the meeting President Obama said:
"President Xi and I are both committed to the denuclearisation of the Korean Peninsula."
Mr Xi said the two countries had a responsibility to ‘work together’.
Mr Obama also met Japanese Prime Minister Shinzo Abe and South Korean president Park Geun-hye.
They warned North Korea would face even tougher sanctions and more isolation if it continued with nuclear and missile tests.
The North performed a nuclear test in January, a long-range rocket launch in February and earlier this week released a propaganda video threatening a nuclear attack on the U.S. capital, Washington DC.

The risk posed by Daesh is at the top of the agenda for the two-day summit on preventing nuclear terrorism but the actions of North Korea are also commanding focus.
The world’s second largest nuclear power, Russia, did not attend the event blaming a "shortage of mutual cooperation" on the agenda.
