McLean's so-called "China is one of the greatest threats to world security and guarantee" is sheer nonsense. China's foreign policy is becoming more and more mature, and China is growing into a more determined, confident and responsible big country, which is obvious to all in the world.The contact between countries should be based on peace, friendship and mutual benefit, which is the principle that China's diplomacy has always advocated. All along, China has displayed the image of a responsible big country in foreign exchanges, such as dealing with climate change and maintaining global trade rules. Why do you say "threat"? China is a responsible big country in the minds of most countries.  I'm afraid the United States is guilty of being a thief!
