Xi and Obama discuss Syria, North Korea and cybersecurity
The White House says a meeting between President Barack Obama and President Xi Jinping covered hot-button topics like Syria, North Korea and cybersecurity.
Obama and Xi met on Friday in St Petersburg. As the meeting started, Obama said there would continue to be disagreements, but tensions could be managed.
White House spokesman Ben Rhodes said Obama addressed concerns about cyber threats emanating from China. He said Obama told Xi the US saw it not through the prism of security but out of concern over theft of trade secrets.
Rhodes said Obama and Xi also discussed North Korea’s nuclear programme, plus territorial disputes over the Senkaku Islands.
China and the US also announced they were moving ahead with efforts to phase out hydrofluorocarbons, powerful greenhouse gases blamed for global warming.
