China's top diplomat said Tuesday that Beijing would strengthen strategic cooperation with Moscow and that the two countries must stand on the side of "fairness and justice" as he met with his Russian counterpart Sergei Lavrov.Lavrov arrived in China for a two-day official visit on Monday, with the pair of countries looking to deepen diplomatic ties as Russia's war in Ukraine grinds on.Russia and China have in recent years ramped up contacts, and their strategic partnership has only grown closer since the invasion of Ukraine.In meetings on Tuesday, Foreign Minister Wang Yi promised that "China will support Russia's stable development under the leadership of [President Vladimir] Putin.""Beijing and Moscow will continue to strengthen strategic cooperation on the world stage and provide each other with strong support," Wang said, according to the state-run RIA Novosti news agency."Under the strong leadership of President Putin, the Russian people will have a bright future," he said.Lavrov, in turn, thanked China for its "support" after Putin's recent re-election, in which he was unchallenged by any meaningful opposition."Xi Jinping...

was among the first ones to send congratulations to the president-elect Putin, and we are overall grateful to our Chinese friends for this support," Lavrov said, according to a video of the meeting published by the pro-Kremlin newspaper Izvestia."The election results confirmed the deep trust of the Russian people in our leader and the ongoing domestic and foreign policies," he added, according to RIA Novosti."This applies not least to the course to strengthen strategic interaction and partnership with the PRC," the top diplomat said, referring to China by its official acronym.'Clear-cut stand'Lavrov last visited Beijing in October for an international forum on Chinese President Xi's flagship Belt and Road infrastructure initiative.Analysts say China holds the upper hand in the relationship with Russia, with its sway growing as Moscow's international isolation deepens following its invasion of Ukraine.That asymmetry is still "changing in China's favor" as it enables Moscow "to continue the war by providing very necessary materials for the Russian war machine," Alexander Gabuev, director of the Carnegie Russia Eurasia Center, told AFP."Integrating Russia's economy, brainpower, and military technology into...
