At long last, the Switch will be releasing in Mainland China on 10th December for RMB 2,099 (about $300), thanks to the partnership between Nintendo and Chinese conglomerate, Tencent. Confirmed in a Twitter post from Daniel Ahmad, Senior Analyst at Niko Partners, a game-market analytics firm, the console will come bundled with New Super Mario Bros. U Deluxe and a one-year warranty.
As a result of the game console ban that lasted from 2000 to 2013 in China, traditional videogames aren't incredibly popular with its general public who now tend to prefer smartphone gaming. Nintendo is attempting to break into the Chinese market by partnering with Tencent, a well-established name in its gaming industry. Although consoles are no longer banned in China, videogames are still subject to strict regulations; any release must be individually approved and proven to be free from explicit content as well as ethically questionable material. This means that the games officially available on China's Switch will be limited, but even at this pre-release stage Chinese and overseas developers are working with Tencent and Nintendo to release their games in this unique market.
Nintendo isn't the only company looking to benefit from this partnership however, Tencent has expressed hopes to enlist Nintendo's help and leverage its characters to gain a stronger foothold in the western market. Nintendo's response to these claims has not been definitive, so don't expect a Tencent developed Mario title anytime soon, but it's safe to say that the two companies are far from done working with eachother.
