The Chinese official also suggested the UK had been muscled by the US into banning Huawei technology from the British 5G network. Mr Liu made his comments in a long series of tweets early this morning, following a phone call between UK Foreign Secretary Dominic Raab and Chinese Foreign Minister Wang Yi.
The two officials had an ‘in-depth’ discussion about China-UK relations.
Tobias Ellwood, Chair of the Defence Select Committee, recently warned tensions between the two nations are so strained that ‘Cold War II’ has “already started”.
The defence official also called for a “full foreign policy strategic reset” towards China.
It comes amid a number of serious disagreements between China and Britain on a number of issues including Hong Kong and the UK’s 5G network.
However, Mr Liu today claimed such a reset would be impossible.
He said in a tweet: “Some people in the UK called for a ‘reset’ of the China-UK relationship with a view to starting all over again.
“This will only lead this relationship to a dead end.
“At this crossroads, our two sides should act in a reasonable and mature way, remain committed to the basic norms governing international relations, respect each other’s core interests and major concerns, and safeguard the political foundation for our bilateral relationship.”

Mr Raab called China’s Hong Kong law “a clear and serious violation of the UK-China Joint Declaration and with it a violation of China’s freely assumed international obligations.”
The foreign secretary also called the measures a “flagrant assault on freedom of speech and freedom of peaceful protest for the people of Hong Kong.”
As a result, the UK has offered an easier path to UK citizenship for Hong Kong residents, as well as placing an arms embargo on the region.
Today, Mr Liu referred to the UK’s comments and actions as in violation of international conduct.
He said: “The UK’s recent remarks and actions with regard to the National Security Law for Hong Kong SAR violated the basic norm governing international relations, namely, non-interference in other countries’ internal affairs. China strongly opposes this.
“The National Security Law is totally in line with China’s Constitution and the Basic Law of HKSAR. It not only safeguards a high degree of autonomy and prosperity and stability in HK, but also protects the legitimate and lawful rights & interests of all foreign businesses and people in HK.”
Regarding 5G, Mr Liu said both countries should “provide a level playing field” for businesses.
However, he said: “Regrettably, the UK’s decision under pressure and coercion from a certain country was politicisation of a business issue and discrimination against China.”
