The United Nations Secretary-General, Antonio Guterres has warned China and United States to avoid new Cold War, imploring two major powers to repair their completely dysfunctional relationship.

In an interview to Associated Press, he urged the world’s two major economic powers to cooperate on climate and negotiate more robustly on trade and technology even given persisting political fissures about human rights, economics, online security and sovereignty in the South China Sea.

He said the US-Britain deal to give Australia nuclear-powered submarines so it could operate undetected in Asia is just one small piece of a more complex puzzle created completely dysfunctional relationship between China and the United States.
