The US decided to deploy anti-missile defence system to South Korea and this raised tensions between US and China.
Communist party chiefs in Beijing are furious that the US has sent its formidable high-altitude area defence (Thaad) anti-missile system to shoot down North Korean missiles.
The deployment comes after the hermit state’s dictator Kim Jong-un spent the last few years test firing long-range missiles and just last month he tested yet another nuclear bomb.
The US – afraid North Korean missiles may one day hit its west coast cities – has vowed to protect its alley in the south.
But the plan has outraged Chinese military bosses.
They deeply resent a strong US military presence in its backyard and is paranoid the anti-missile system could be used to neutralise its missiles.
The Communist state backs neighbouring North Korea, in part because it fears if the state collapses it will bring chaos to its doorstep and increase US power in the region.
Experts believe war has already been brewing between China and the US who are both arming themselves to the teeth in preparation for a future world war showdown in the Pacific.
Tensions are growing over Beijing claims to islands in the South China Sea that its neighbours insist belong to them.
The US deployment of missiles to South Korea can only inflame tensions further.
Tellingly, a comment piece for the People’s Daily, the official media outlet for the Chinese Communist Party, read: “If the United States and South Korea harm the strategic security interests of countries in the region including China, then they are destined to pay the price for this and receive a proper counter-attack.
“Like any other country, China can neither be vague nor indifferent on security matters that affects its core interest.”
The robust remarks come after Chinese Foreign Minister Geng Sahuang called on the US and South Korea to halt plans, which will reportedly be stationed at a golf course in the south east of the country.
He said: “We keep repeating our position that the deployment of the THAAD missile system by the United States and the Republic of Korea will not address the concerns of relevant parties, contribute to denuclearisation on the Korean Peninsula, or aid the peace and stability of the Peninsula.”
Mr Geng showed no signs of backing down, warning China would take “necessary measures to safeguard its national security”.
