Chinese Ambassador to the UK Liu Xiaoming on Wednesday urged European politicians to stop interfering in the affairs of Hong Kong Special Administrative Region (HKSAR). 

"China has never interfered in other countries' internal affairs and we strongly oppose interference in China's internal affairs by any country," Liu said at a webinar with UK think tanks.

Last month, the Standing Committee of China's National People's Congress adopted the National Security Law for Hong Kong SAR to deal with the enormous risk Hong Kong faces in safeguarding national security. 

The law, he explained, is aimed at preventing, suppressing and punishing four types of criminal activities: secession, subversion, terrorist activities and collusion with a foreign country or with external elements to endanger national security.

Liu said nearly 3 million Hong Kong citizens have signed a petition in support of the law, and more than 70 countries in the world, including some European countries, have voiced their support. 

However, some European politicians have made irresponsible remarks regarding this law to interfere in Hong Kong affairs, which are internal affairs of China, he pointed out. 

He said he hopes the EU side can view the National Security Law for Hong Kong SAR from an objective, reasonable and fair perspective and take concrete steps to observe international law and basic norms governing international relations.

Speaking on UK's 5G ban on Huawei, Liu said the decision was "disheartening." 

"Now I would even say this is not only disappointing – this is disheartening," Liu said, adding that Britain had "simply dumped this company."

"The way you are treating Huawei is being followed very closely by other Chinese businesses, and it will be very difficult for other businesses to have the confidence to have more investment," he said.
