The Trump administration is spending billions of dollars on deals with ownership stakes in companies. The unusual practice shows no sign of slowing.

The changes would make it easier for American firms to obtain key minerals, delivering on what the White House said the two countries had agreed to at last month’s summit.

The Chinese government followed through on promises it made publicly after a recent summit, but has not yet taken other actions sought by the White House.

Drones, missiles and other crucial components of Europe’s rush to rearm itself rely on an increasingly unsteady supply of minerals from China.

China has suspended export controls announced this month, but was conspicuously silent about rules imposed earlier, which are snarling global supply chains.

President Trump and the Chinese leader Xi Jinping are being described as “irreplaceable” and “world class leaders” before a meeting seen as critical for shoring up a trade truce.

The U.S. announced agreements on Sunday with Malaysia, Thailand and Cambodia, securing support for its efforts to pressure China on trade and critical minerals.

China’s far-reaching rules already affect manufacturers of semiconductors, cars and many other products. They will soon become much broader.
