On November 7, 2016, the Standing Committee of the National People’s Congress (NPC) of the People’s Republic of China (PRC) passed the final Cybersecurity Law (CSL) after three rounds of review by the NPC since June 2015. China’s first law addressing the cybersecurity issue, the CSL’s promulgation marks China’s increasingly stricter administration and supervision of cyber space, and is a milestone for China’s cybersecurity legislation. The CSL will come into effect on June 1, 2017. Given the potential impact of the law, we suggest clients review it closely, especially when transmitting affected data out of the PRC.
