Those companies you listed, especially DJI and Anker, are the exception rather than the rule. In my experience living there for 6 years, Chinese companies at all levels tend to cut corners too easily and focus on short-term profits. Very few are capable or willing to put in what it takes to establish a brand that can compete with Western brands. DJI was helped by being in a relatively new market without long-establish brands, Anker to a similar extent (and also produces less expensive products). It's much easier to buy a foreign brand (like Geely with Volvo) than to try to establish your own brand internationally. Even huge companies like BYD, Huawai, and Xiomi (smaller but very popular in China) have not made headway except in less developed countries.
