China has vowed to deepen its support for Russia after Donald Trump threatened to impose tariffs on Moscow’s trading partners. Xi Jinping, China’s president, said that Beijing and Moscow should “strengthen mutual support on multilateral forums” after meeting Russian foreign minister Sergei Lavrov in Beijing.

Trump’s threats of secondary tariffs are “never going to go anywhere” as long as he is unwilling to impose costs on Moscow directly, Keir Giles, a senior fellow at the London-based Chatham House think tank, told NBC News Monday.
