SEATTLE – Chinese President Xi Jinping will meet U.S. tech titans and tour Boeing's biggest factory and Microsoft's sprawling campus near Seattle this week as he kicks off a U.S. visit that includes a black-tie state dinner at the White House hosted by President Obama.

U.S. government and business leaders aim to strike a balance between forging agreements and improving relations with the world's second-largest economy, while sending strong messages about allegations of Chinese cyber spying and intellectual property violations as well as Web censorship and China's disputed territorial claims to islands in the South China Sea.

For the Chinese side, Xi's meetings with Obama and U.S. business leaders offer the chance to bolster the president's stature at home, building on a high-profile military parade earlier this month to mark the end of World War II, while deflecting attention from the country's recent stock market rout, slowing economy and a chemical explosion at a Tianjin warehouse that killed more than 160 people.

No policy breakthroughs are likely during Xi's U.S. trip, which will begin with meetings with executives in Seattle and end with a speech at the United Nations General Assembly in New York on Monday.

In comments in the Wall Street Journal before his arrival, Xi said China's government does not engage in theft of commercial secrets or support companies that do. He also said China's economy faces downward pressure but is still operating within a proper range, adding exchange rate reform will continue and there was no basis for sustained depreciation in the yuan.

While in Seattle on Wednesday, Xi and top leaders from China's Internet regulator and tech firms are expected to meet leaders from Microsoft, Apple Inc., Amazon.com Inc. and other tech companies seeking to expand access to the Chinese consumer market.

Even if no formal agreements are reached, the presidential blessing "sends an important message to Chinese leadership" to help them, said Ed Lazowska, Bill and Melinda Gates chair of computer science at the University of Washington.

For Boeing, the visit could bring a formal announcement of plans for an aircraft finishing plant in China. The plant would help Boeing's Chinese sales, analysts say, and counter a threat from Commercial Aircraft Corp. of China Ltd., which is developing a single-aisle aircraft to challenge the top-selling Boeing 737 and Airbus A320 planes. Airbus opened an assembly line in China in 2008 and recently won a landmark, $11 billion order from China.

Prospects for broad policy changes from Xi's trip appear limited. The U.S. Chamber of Commerce expressed disappointment on Monday at the failure to narrow disagreement on a bilateral investment treaty that would open more Chinese business sectors to U.S. investment. The U.S. also wants to build on climate change commitments and agree on new rules to cut the risk of confrontation in the Asia-Pacific region, U.S. and Chinese sources have said.

China's slowing economic growth has raised questions about Xi's economic stewardship and puts him in a more difficult position than when he and Obama met last November in Beijing.

Washington has threatened sanctions against Chinese individuals and companies that have been accused of hacking U.S. corporate databases.

On the eve of Xi's visit, U.S. Treasury Secretary Jacob Lew urged China to reaffirm its commitment to moving toward a market-oriented, consumer-driven economy.

In an article in the Wall Street Journal, Lew said questions remain about the business climate in China because of Beijing's restrictions on the purchase of foreign technology and its review process for foreign investment. He also cited concerns about China's currency valuation policies.

On Monday, Washington state announced four cooperation agreements would be signed with entities from China, including plans to promote trade, investment and clean energy research.
