Amid growing condemnation of Russia’s invasion of Ukraine, Chinese Foreign Minister Wang Yi issued what is arguably his country’s strongest statement of support for Moscow since the beginning of the crisis.

Wang declared ties with Russia to be “rock solid,” noting that no matter how precarious the situation may be, “China and Russia will maintain a strategic focus and steadily advance our comprehensive strategic partnership and coordination.”

Wang’s remarks on March 7 can also be seen as efforts by Beijing to step up support for Moscow and its push to challenge U.S. dominance, especially as Russia’s economy becomes increasingly isolated because of international sanctions.
