South Korean gaming stocks, including Netmarble Corp (251270.KS), NCSOFT (036570.KS), Krafton (259960.KS), Kakao Games (293490.KQ) and Devsisters (194480.KQ) jumped between 2% and more than 17% in morning trade on Thursday, a day after Chinese authorities granted publishing licenses.The approval of imported games effectively marks the end of China's crackdown on the video game industry which began in August last year when regulators suspended the game approval process.Unlike in most other countries, video games need approval from regulators before release in China, the world's largest gaming market.The year-long crackdown on the industry has dealt a significant blow to Chinese tech companies including Tencent and NetEase Inc (9999.HK) which derive substantial revenue from publishing both self-developed and imported games.Through various affiliated companies, Tencent, the world's largest gaming company, has effectively received a total of six licences in December, a source with knowledge of the matter told Reuters."
