Viruses know no borders, and epidemics do not discriminate between races, he said, adding that only through unity, coordination and a joint response can the international community conquer the pandemic and safeguard the common home of human beings.

The pandemic is only temporary, but cooperation is everlasting, Xi said, adding that while COVID-19 has posed challenges to China-Kazakhstan cooperation, it has also spawned new opportunities.

He called on both nations to expand cooperation in sectors such as the digital economy and healthcare and to foster new sources of growth for bilateral ties.

Tokayev said the Chinese people, under the wise leadership of Xi, have accomplished outstanding achievements in epidemic containment, which also has given confidence and hope to people around the world.

The world has witnessed the remarkable level of China's healthcare system and the high level of professionalism among its medical workers, and China has again showcased its highly efficient governance capacities in dealing with complex difficulties and challenges, he said.

During the conversation with Polish President Andrzej Duda, Xi hailed the people as the true heroes in serving as the source of strength and confidence for China to fight the virus. Xi said the 1.4 billion Chinese people have put up a tenacious fight with great solidarity and steadfast resolve.

Duda praised China's timely, decisive and rigorous epidemic containment measures and expressed his admiration for the Chinese people and medical workers.

Noting that China has a solid economic foundation, Duda said he is fully confident that China will overcome the epidemic and achieve better development.

Xi told Brazilian President Jair Bolsonaro that the international community has already reached a consensus that China made enormous sacrifices in the fight against COVID-19 and bought precious time for the world.

Bolsonaro said the Brazil-China friendship and the two nations' comprehensive strategic partnership are unbreakable.
