US President Joe Biden and Chinese President Xi Jinping have had a long telephone conversation.

While Beijing has spoken of cooperation, Washington has expressed concern. "If we don't move, they'll share our food," Biden warned senators in a phone call during a meeting with senators on Wednesday night.

Comparing himself to China, Biden said, "China has invested billions of dollars in transportation, the environment and development in various fields."

We need to take action in these areas. At the same time, Biden expressed concern about Beijing's repressive and other trade. He also called for an end to human rights abuses in Taiwan, Hong Kong and Xinjiang. Earlier on March 27, former US President Donald Trump spoke with Chinese President Hu Jintao.

Since then, economic relations between the two countries have been strained.
