The missile test comes as President Lee Jae Myung arrives in Beijing to meet his Chinese counterpart, Xi Jinping, their second in two months.

North Korea has launched multiple ballistic missiles off its east coast into the sea as South Korea’s leader begins a state visit to China in its first barrage of the new year.

According to South Korea’s military, the missiles launched at about 7:50am on Sunday (22:50 GMT on Saturday) flew about 900km (560 miles).

The military added that the country, as well as the United States, was “closely analysing the specifications” while “maintaining a full readiness posture”.

In a statement, the US forces for the Asia Pacific said the missile launches did not pose an “immediate threat to US personnel or territory, or to our allies”.

Japan also reported that at least two missiles had reached distances of 900km (560 miles) and 950km (590 miles).

“North Korea’s nuclear and missile development threatens the peace and stability of our country and the international society, and is absolutely intolerable,” Japan’s Defence Minister Shinjiro Koizumi told reporters.

The last time Pyongyang tested its ballistic missiles was on November 7.

According to North Korean state media, leader Kim Jong Un on Saturday called for the doubling of production capacity of tactical guided weapons while visiting a munitions factory.

In recent weeks, Kim has visited a series of weapons factories and a nuclear-powered submarine, overseeing missile tests in advance of the ninth party congress of the Workers’ Party, which will take place later this year and set out key policy goals.

Lim Eul-chul, a professor at the Institute for Far Eastern Studies in Seoul, told the Reuters news agency the launches from Pyongyang represented “a message to China to deter closer ties with South Korea and to counter China’s stance on denuclearisation”.

Lim added that it was North Korea sending a message of strength that they were different from Venezuela, after the US launched a series of attacks on Saturday and “captured” President Nicolas Maduro.

China visit

On Sunday morning, Chinese state broadcaster CCTV reported that South Korean President Lee Jae Myung had arrived in Beijing on a four-day visit.

Lee, accompanied by more than 200 South Korean business leaders, is expected to discuss supply chain investment, the digital economy and cultural exchanges.

The South Korean leader will meet his Chinese counterpart, Xi Jinping, for their second meeting in just two months. According to analysts, the short frequency of the meetings signals Beijing’s interest in increasing economic collaboration and tourism.

Seoul has said peace on the Korean Peninsula would be on the agenda during the Beijing trip.

Lee’s trip comes at a time of heightened tensions between China and Japan after Japanese Prime Minister Sanae Takaichi said in November that her country’s military could get involved if China were to take action against Taiwan.

Before his trip, Lee gave an interview to CCTV, in which he assured that South Korea consistently respects the “One-China” policy when it comes to Taiwan. He said the healthy development of Beijing-Seoul relations depends on mutual respect. Lee also praised Xi as a “truly reliable neighbour”.
