From students to tech: How US-China ties are sliding despite tariff truce

US Secretary of State Marco Rubio's salvo against Chinese students, promising to "aggressively revoke" their visas, is the latest move in heightening tensions between the world's two largest economies. Despite a temporary tariff truce reached between them earlier this month, divisions between Washington and Beijing remain wide, with recent ruptures over higher education, artificial intelligence (AI) chips and rare earth minerals. Here's all we know about how relations between China and the United States are worsening despite diplomatic efforts. A US-China trade spat escalated after Trump's administration raised tariffs on Chinese goods to 145 percent earlier this year, with cumulative US duties on some Chinese goods reaching a staggering 245 percent. Under an agreement reached on May 12 following two days of trade talks in Geneva, tariffs on both sides were dropped by 115 percentage points for 90 days, during which time negotiators hope to secure a longer-term agreement.
