US President Joe Biden said on Thursday that his first phone call with Chinese leader Xi Jinping since taking office lasted two hours. "Last night, I was on the phone for two straight hours with Xi Jinping," Biden told reporters. It was an unusually long interaction for a US president. Biden warned afterwards that if the United States doesn't "get moving" on China policy, "they're going to eat our lunch." He challenged President Xi on human rights, trade and regional muscle-flexing during the call, which aimed at setting the tone for the US-China relationship.
