The biggest highlight in China's foreign relations has been "head-of-State diplomacy", State Councilor and Foreign Minister Wang Yi said on Sunday.

Through innovative "cloud diplomacy", President Xi Jinping has championed solidarity in the world's fight against COVID-19, and pointed the way forward for the international community to jointly fight the virus, Wang said.

In the past year, China has been firm to safeguard national interests and resolutely opposes hegemony and bullying practices, as well as external interference in domestic affairs, he added.
