The United States and China vowed to make progress on disagreements over cyber hacking and economic disputes as they wrapped up two days of high-level talks in Beijing.

The sixth round of the U.S-China Strategic and Economic Dialogue addressed issues ranging from climate change and cybersecurity to economic reforms and diplomatic tensions with China’s neighbors.

U.S. Secretary of State John Kerry said Thursday he had a “frank” discussion with his Chinese counterparts about cyber attacks, which he said are hurting American companies.

China rejects U.S. charges that it is stealing intellectual property from U.S. companies, instead accusing the U.S. of conducting its own espionage against Beijing. 

Thursday’s talks began with a breakfast that included entrepreneurs from the United States and China.

At a time when there are continuing tensions between the two nations, many see economic cooperation as a key opportunity.
