DONGGUAN, China — President Trump and China’s leader, Xi Jinping, are expected to try again to resolve their tariff war when they meet in Japan on Saturday.

First, they will need to figure out what to do about Huawei.

The Trump administration has squeezed the Chinese technology giant with nearly the full might of the United States government, choking off the firm’s access to vital American suppliers, barring it from the country’s telecom market and filing sweeping criminal charges against it.

Though Washington officials say those moves arose from national security concerns and are separate from the trade fight, few expect China to accept a deal to lift punishing tariffs that does not include relief for its biggest, most internationally successful tech firm.

“It is almost impossible for the Chinese to agree to almost anything while the Huawei action looms,” said Samm Sacks, a China expert at the think tank New America. “Even if this is walked back, the Chinese fundamentally mistrust this administration. At this point, there’s no walking back this mistrust.”
