I think there might be some confusion between Cheng Shin AKA Maxxis and Chengshan,
Cheng Shin is in Tiawan or the Republic of China.
They operate under the Maxxis banner.
Cooper had a Chinese division known as Chengshan Rubber (Shangdong) in the Peoples Republic of China.
Also they had a partnership with Kenda which is in Taiwan.
Convoluted I know.........
Cooper is/was being bought by Apollo out of India.....but I think the deal is falling apart
