In late September, Chinese President Xi Jinping made his first state visit to the United States. Cybersecurity and climate change dominated the bilateral announcements during his visit, but U.S.-China investment treaty negotiations, which have been underway since 2008, may have also advanced.

Prior to President Xi's visit, President Obama expressed opposition to Chinese electronic commercial espionage, such as the theft of trade secrets, and noted that the administration was preparing countermeasures. During President Xi's two days in Washington, DC, Presidents Obama and Xi announced that their countries had agreed not to conduct or support cyber-theft of intellectual property, and to increase cooperation for cybercrime investigations. However, President Obama stated that he had informed President Xi that the United States would apply sanctions against cybercriminals if needed.

The leaders also issued a joint statement on climate change, and China announced that it would begin implementation of a nationwide cap-and-trade system for greenhouse gas emissions in 2017. This follows emissions-reduction targets that China announced during President Obama's state visit to Beijing last year, as well as smaller municipal and provincial cap-and-trade programs that China has implemented over the last several years.

Before beginning bilateral discussions in Washington, DC, President Xi spent time in Washington state, where he met with U.S. and Chinese business leaders. President Xi promised reforms that would expand trade relations between the two countries, and emphasized the continued strength and resilience of the Chinese economy. Boeing announced Chinese orders and commitments for 300 planes that were made during President Xi's visit to the company's plant in Everett, Washington. These aircraft will be finished in China, at Boeing's first international airline assembly plant.
