It has great significance for the G20 members, which contribute 85 percent of global GDP, to make joint efforts to prevent a global economic recession, Jin said.

The leaders of G20 nations will be joined by their counterparts from some invited countries, including Spain, Jordan, Singapore and Switzerland, as well as major international organizations, including the United Nations, the International Monetary Fund and the World Health Organization.

On Monday, G20 finance ministers and central bank governors convened in a virtual meeting, during which they agreed on measures to reduce the impacts of the disease on the global economy.

Xi said on Wednesday during a phone conversation with German Chancellor Angela Merkel that China is willing to bolster coordination and cooperation with all other parties to send out voices of solidarity and unity in fighting COVID-19 and to shore up global confidence.

He urged more coordinated macroeconomic policies between countries to stabilize markets, growth and employment and to guarantee public well-being.

Merkel said G20 members should step up coordination and cooperation, support each other and take up a leading role in conquering the crisis and stabilizing the global economy.

Germany hopes to cooperate with China in the research of vaccines and pharmaceuticals and set an example of uniting to fight the pandemic, she said.

On Tuesday night, Xi held telephone conversations with the presidents of Brazil, Kazakhstan and Poland.

During the conversations with the leaders, Xi reiterated China's vision of a community with a shared future for mankind and the need for a united global coronavirus response.

He also highlighted China's dedication to working together with different countries in safeguarding global public health security and contributing its efforts to curb the global spread of the virus.

He also pledged China's firm support and help to the three countries in fighting COVID-19.

The response to the global public health crisis has further amplified the urgency and importance of building a community with a shared future for mankind, Xi said while speaking with Kazakh President Kassym-Jomart Tokayev.
