The North Korea’s foreign affairs representative Pak Yun said: “The situation on the Korean peninsula is close to the brink of war because of endless military exercises by American and South Korean forces targeting us.
“Now, Britain has decided to send its Typhoon fighter jets to take part in joint US-South Korean military drills, in the south of Korea, from 4 to 10 November.
“This is a hostile act, openly joining the US and South Korean forces in moves for a new war against us.
“Britain claims that this military exercise is not targeting us, but the US and South Korea openly say that these military exercises are aimed at launching a strike against our military facilities and our command structure.”
Mr Pak Yun also said that Britain should learn from its past when it took part in the Korean war and suffered losses.
Britain has announced that it will send military planes to Asia to take part in exercises in South Korea.
North Korea has increased its opposition to military exercises and has launched more than 20 missiles and two nuclear tests this year.
China’s defence ministry has also urged the US to take care and not worsen regional tensions with its navy drills.
China claims that the US anti-missile system in South Korea will threaten its own security and not calm things down with nuclear-armed North Korea.
According to Seoul and Washington, the missile system is simple designed to act as a defence against North Korean missiles and are not aimed at Beijing.
China’s Defence Ministry said it was “paying close attention” to the joint US South Korean naval drills.
The Ministry said: “We hope the relevant sides remain calm and exercise restraint, and not do anything to exacerbate regional tensions.”
Tensions in Korea have been high since North Korea’s fourth nuclear test in January and the succeeding satellite launch, missiles tests and a nuclear test last month.
Beijing has become enraged by Korea’s nuclear and missile tests and has urged stronger United Nations sanctions against Pyongyang.
