China has told the United States it wants to see all sides involved in Ukraine remain calm and avoid increasing tension while the United States stressed de-escalation and warned of the security and economic risks from Russian aggression.

Beijing’s Foreign Minister Wang Yi and U.S. Secretary of State Antony Blinken spoke about Ukraine on a telephone call late on Wednesday.

We call on all parties to stay calm and refrain from doing things that agitate tensions and hype up the crisis, Wang told Blinken, China’s foreign ministry said in a statement.

Russia, which has been building up its forces on Ukraine’s borders for months, has demanded NATO pull back troops and weapons from eastern Europe and bar Ukraine, a former Soviet state, from ever joining the alliance.

The United States and its NATO allies reject that position but say they are ready to discuss other topics such as arms control and confidence-building measures.

Secretary Blinken conveyed that de-escalation and diplomacy are the responsible way forward, Mr. Blinken was quoted as saying to Mr. Wang in a statement issued by the U.S. state department.

Global security and the economic risks posed by further Russian aggression against Ukraine figured in the talks, the department said.

Mr. Wang, apparently referring to Russia’s objections to NATO’s expansion in eastern Europe, told Mr. Blinken that one country’s security could not be at the expense of the security of others and regional security could not be guaranteed by strengthening or even expanding military blocs, his ministry said.
