If all you can point out is stuff "in China for China" then you aren't strengthening your case. Linux isn't made "in Finland for Finns", Windows isn't made "in the US for Americans," QNX isn't made "in Canada for Canadians," and so on. When you are really good at something, you export it and sell it worldwide. You see that with US and European (as well as other) software, just like you see it with Chinese SMPSes. When you are really good in this interconnected world you cross borders, you aren't only able to sell in a rather walled off, controlled market. Canon, Zeiss, Leica, Nikon, etc don't sell glass just in their native countries or regions, they are the worldwide leaders because they are good. You find Canon cameras for sale through out the world, not just in Japan.
Baidu is probably actually the best example: It is such a huge force in China, yet nobody outside China uses it. Everyone else uses Google (or to a much lesser extent Bing and Yahoo). Despite Google being an American company in origin, their product is not limited to one country. It isn't limited to English speakers either, you find it all over the world. In fact the only places it doesn't have a lot of penetration are places like China, Iran, North Korea and so on.
Why? Because China wants to maintain control on the information their populace can see. So Baidu, being local, works well for that. Google, being global, does not. That combined with a bunch of protectionism means that Baidu is the big thing in China. But that's artificial, it isn't because Baidu is so amazingly great. You can get to Baidu from the US no problem, but few people do because it is a Chinese only site, you go to the homepage and it is in Chinese with no apparent way to change languages. By contrast Google picks a language based on your country location (which you can easily change) and supports searches in essentially every language, including Chinese.
When you look at the heavy hitters in tech, Chinese companies just don't make the list except extremely rarely. Let's take a quick look at a few major areas:
OSes: Windows (US), Linux (Finland, though worldwide really), OS-X (US), iOS (US), Android (US), QNX (Canada), BSD (US/worldwide), vxWorks (US).
CPUs: Intel (US), AMD (US), ARM (UK), MIPS (US), Power (US), Hitachi (Japan).
Databases: Oracle (US), MySQL (Swedish, though US now), Postgres (US/global), MSSQL (US), DB2 (US).
FPGAs: Xilinx (US), Altera (US), Amtel (US), Lattice (US).
Video Production: Avid (US), Final Cut (US), Premiere (US), Vegas (Japan/US, now moving to Germany).
Video Game Engines: Unity (US), Unreal Engine (US), iDTech (US), Frostbite (Sweden), Source (US), Gamebryo/Creation (US), Cryengine (Germany), Dunia (Canada), PhyreEngine (Japan), Unigine (Russia).
