What??
you dont want the U.S to say you target them? WTO? who gives a **** about WTO nowadays, countries just impose tarriffs/restriction/protectionism anyway. many countries do it and will keep doing it. Even china has done it in some sectors like Internet, Solar, and electronic payment systems like its monopoly of Unionpay(which is now as big as master card/Visa and keeps growing). Countries all practice protectionsm to some extent, when they do other countries might go to WTO and file a complain, this takes years for the WTO to take a decision, and even then the country can apeal it, which again takes time/years for a final one. By this time the said country has already cornered the local market and acquired the scale necessary to go overseas and compete with foreign ones(e.g your Unionpay).
So you just have to stop using WTO excuse admit your government was incompetent on this one. They should have imposed their own OS long ago. and today we wouldnt be talking about Android/IOS in china. in fact maybe they will be competing overseas by now. You say a few years back you lack the technological know how, yes but not that much. In fact i read somewhere that for example your WPS(kingsoft office similar to MS word) was created almost same year as microsoft office and has grown quite well today and is almost as good as MS office but is used mostly internationally, but domestically it still has just about 10% of chinese domestic market while MS office corners over 75-80%. Do you see the irony here?
Your CCP doesnt even encourage its own local tech companies properly, same with IBM who dominates your server market and has recently won several contracts recently with your largest bank ICBC for their data storage (soon all your banking system data will be analysed at the pentagon/CIA.
) even though i read an equivalent called Inspure or something(dont know if i spell it right)
Believe me if this was say in Japan it will be the dominant one as i know Japanese are very nationalistic and tend to favour their local companies irregardless of if their product may lag a little behind those of the west or not..
