Chinese President Xi Jinping arrives in Washington today for a three-day state visit. Export controls will be a central focus of his meeting with President Trump. Two moratoriums, one on U.S. controls on advanced semiconductors needed by Chinese tech firms and one on the reciprocal Chinese controls on rare earth minerals, are set to expire on November 10. A major question is whether, and for how long, those moratoriums will be extended. As the visit begins, it’s worth remembering that both nations have an interest in restarting open trade in these minerals.
