China has called on United States to withdraw its troops in a responsible and orderly manner to ensure smooth transition in Afghanistan and to prevent further violence following US President Biden's announcement of American troops withdrawal before September 11.

Chinese Foreign Ministry Spokesperson, Zhao Lijian said during his briefing at International Press Center that the current security situation in Afghanistan is still complex and grim and the problem of terrorism is far from being solved.

Terming the US as the biggest external factor affecting the issue of Afghanistan, he said, the relevant decisions and actions of the US should fully respect the sovereignty and independence of the territorial integrity of Afghanistan.
