The affairs of China's Hong Kong Special Administrative Region (HKSAR) are China's internal affairs and gross interference in Hong Kong affairs can only undermine the sound implementation of the policy of "One Country, Two Systems," Chinese State Councilor and Foreign Minister Wang Yi said in an exclusive interview with Xinhua News Agency on Wednesday.

Non-interference in other countries' internal affairs is a basic norm governing international relations, and no country will allow other countries to flagrantly sabotage its sovereignty and territorial integrity, Wang said in the interview responding to the claim made by the United States that China has given up the "One Country, Two Systems" policy as it passed the national security law for HKSAR.

The Chinese Foreign Minister said that China is committed to the policy of "One Country, Two Systems."

"With the strong support from the mainland, an improved legal environment and the united efforts of our Hong Kong compatriots, we can surely uphold and better implement the policy of 'One Country, Two Systems,'" he said.

Any gross interference into Hong Kong affairs, in words or action, will be met with firm rejection from all Chinese people, including the people of Hong Kong, the Chinese foreign minister said.

The national security legislation underpins the foundation of the security of any country, and it is a common legal practice of all countries, the Chinese foreign minister said, stressing that the legislation on safeguarding national security in Hong Kong has plugged the long-standing legal loopholes in Hong Kong. 

"It will ensure both the long-term implementation of the policy of 'One Country, Two Systems' on the basis of rule of law and durable security and stability of Hong Kong," Wang said, citing that several million residents of Hong Kong signed a petition in support of the legislation, which demonstrates their longing for peace and stability in Hong Kong and their strong support for the national security legislation.
