Chinese President Xi Jinping will meet U.S. tech titans and tour Boeing Co's biggest factory and Microsoft Corp's sprawling campus near Seattle this week as he kicks off a U.S. visit that also includes a black-tie state dinner at the White House hosted by President Barack 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 Two, while deflecting attention from the country's recent stock market rout, slowing economy and a chemical explosion at a Tianjin warehouse that killed over 160 people. No policy breakthroughs are likely during Xi's U.S. trip, which is due to begin with meetings with executives in Seattle and end with a speech at the United Nations General Assembly in New York on Sept. 28. In comments published 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, Xi and top leaders from China's Internet regulator and tech firms are expected to meet leaders from Microsoft, Apple Inc, Amazon.com and other tech companies seeking to expand access to the Chinese consumer market.
