According to Reuters, "Taiwan wants to join a major anti-hacking drill conducted by the United States to strengthen cyber security ties with its staunchest ally, its vice premier said on Monday, a move which would help safeguard against constant targeting by hackers in rival China. Many hacks into Taiwan systems have been traced to sites belonging to China's People's Liberation Army, Vice Premier Simon Chang told Reuters in an interview, without elaborating on the locations... The drill is held biennially...Taiwan had invited U.S. officials to observe its own mock drill against cyber attacks in 2013. Cooperation between Taiwan and the United States would aim to strengthen defenses against hackers looking to steal government, military and industrial intelligence."
