“The meeting is mostly to discuss the industry cooperation of the two countries, and big companies from China and the U.S., like Google, will all be there,” Mr. Zuo said.

Microsoft, Facebook, IBM, Apple, Uber and Baidu declined to comment, while Alibaba and Google did not respond to requests for comment.

Over the last few years, China and the United States have been engaged in a sort of technological Cold War. American leaders have railed against a series of hackings that they have said emanated from China, and they have called for Beijing to relax the regulations that limit the sale of American hardware and block Internet companies. In turn, China has argued that revelations by Edward J. Snowden, the former contractor who disclosed American government surveillance, show that the United States also hacks Chinese companies and that those attacks justify its restrictive laws against American companies.

At stake is how the global Internet will be managed. While the United States supports an Internet in which companies are allowed to operate worldwide and users are given free online expression, China has said countries should be allowed to force web companies to follow local laws, including censoring content, monitoring users and hosting data about Chinese users within China. By dangling the carrot of market access to American companies that follow its rules, Chinese officials like Mr. Lu want to influence global Internet governance and have its model more widely adopted.

Holding the tech meeting in Seattle can also be cast in Beijing as a sign that the titans of American industry recognize China’s power and give it respect. Abroad, it signals that companies must accommodate Beijing’s wishes to ensure market access.

“This is about putting as much lipstick as possible on the pig in advance of Xi going into Washington where the administration is saying cyberattacks are the problem and the operating environment for U.S. firms is narrowing,” said an industry official with direct knowledge of the planning of Mr. Xi’s trip, who spoke on the condition of anonymity.
