TikTok owner ByteDance has invested RMB 1.1 billion (USD 165.58 million) in online reading firm Zhangyue Technology (SH:603533), or iReader Technology, in exchange for an 11.23% stake in the latter, eyeing a stronger tie-up with the original content developer, according to Zhangyue’s filing with the Shanghai Stock Exchange on Wednesday.
