Martina Navratilova took a jibe at the US president, Donald Trump, ahead of his key meeting with China's President Xi Jinping. The USA and China are two of the biggest superpowers in the world that have been in a tense trade confrontation in the past few months due to Trump's tariffs.In 2025, the Trump administration imposed sweeping tariffs while China responded with retaliatory levies. As part of the 79-year-old American president's policies, the USA has imposed tariffs on several countries across the world, creating an unpredictable market.Ahead of the Trump-Xi meeting, China announced new export restrictions on rare earth materials, tightening controls on their global supply. The move was seen as a strategic signal in ongoing trade tensions between the two nations. Trump was informed about it during a recent press conference, and he responded:"We'll see. I mean, I just heard this a little while ago before we came in. So I haven't been briefed on it."Further, he touched upon the idea of putting a halt to trading with China. "We have import and we have export. We import massive amounts from China. Maybe we'll have to stop doing that," Trump said.A video of his press conference was shared on X.
