I do agree with your point, but I will also add that since more and more western and foreign investors are doing businesses in China, and have established an overseas expansion into the Chinese market, it will be beneficial for many Chinese college graduates to have a full mastery of the English language so they can find job employments in foreign-owned businesses in China. In this case, many of the tactical managers that run these overseas production facilities are foreigners and communicate with the operational managers / supervisors in the English language. For example, the new INFINITI manufacturing site that Japan will be opening in Dalian is hiring Chinese mechanical and automotive as well as Industrial engineers to fill its ranks, and the modicum of communication will be , of course, English. Now, do you think the Japanese tactical and strategic managers will hire: 1) the Chinese engineer who has mastery / high proficiency of the English language in conjunction with a strong engineering background or 2) the Chinese engineer who has low to medium proficiency of the English language , but a strong engineering background? They will select Choice #1. As China rises in global trade , it will only necessitate the mastery of the English language for Chinese technocrats.
In addition, it is rather obvious that the quality of trechnical education in China is questionable. The Xi administration would do well to further invest in improving the quality of education, which , in turn, will directly improve the quality and efficiency of the product: The Students !
