China's attempts to cooperate with the United States to safeguard the strategic stability of cyberspace have been welcomed, as the Chinese mainland and Hong Kong have suffered a series of high-profile cyber attacks this year, according to the latest PricewaterhouseCoopers Global State of Information Security Survey. According to the report, the average financial loss caused by cyber crimes in the region rose 10 percent year-on-year to $2.63 million, compared with a 5 percent decline globally.

In cooperating to safeguard cyberspace, Beijing and Washington could seek the Internet equivalent of the code of safe conduct agreed between their militaries to avoid naval and air encounters, which has helped manage several bilateral disputes.

The two countries should first try their best to not point the finger at each other in case a conflict over cyber security emerges. The latest round of tensions in cyberspace started in early 2013, when American private security company Mandiant released a report, "APT1: Exposing One of China's Cyber Espionage Units", accusing the Chinese military of stealing US intellectual property.
