The United States and North Korea have been warned against escalating rhetoric and making threats against one another، PressTV reported.
China، Russia and Germany were the countries that expressed concern about the status quo.
Chinese Foreign Ministry spokesman Geng Shuang called on both sides on Friday to avoid "going down the old path of alternately showing strength and continuously escalating the situation."
The spokesman said the sides should try to tone down their fiery rhetoric and say things to de-escalate tensions as international concerns grow that the two could start a devastating conflict.
"We call on the relevant parties to be cautious with their words and actions، and contribute more toward easing tensions and enhancing mutual trust،" Geng said in a statement.
Russian Foreign Minister Sergei Lavrov said the rhetoric from Washington and Pyongyang over North Korea's nuclear program was now "going over the top." He said Moscow hoped common sense would eventually prevail.
German Chancellor Angela Merkel said she saw no military solution to North Korea crisis. The escalating rhetoric، she stated، was a "wrong answer" to the North Korea problem.
Tensions over North Korea escalated in July، when Pyongyang twice successfully tested an intercontinental ballistic missile (ICBM) capable of targeting the US mainland.
