There are things that really doesn't fit:
This is an interesting post I'd like to address.
1. On one hand China has had nuclear weapons for quite some time now - thus nuclear power; but they still burn coal and oil. If I'm not to wrong, the Chinese nuclear forces are not to the same standard the Russians are - even at todays reduced standard.
Coal has always been cheaper than nuclear power, even in the West. For a long time china lacked access to overseas resources, so the uranium we had at home went into weapons. Our nukes are quite good today. The DF31A is a very small missile at 40 tons, yet it can deliver a 1 megaton bomb at 12000km. We just haven't built that many of them since we cannot benefit from "racing" Americans.
2. On one hand the chinse vociferously claim to be the best in technology - and on the other they haven't developed a decent civilian airplane yet....
Actually Chinese vociferously claim we need to catch up. It's kind of a way to urge ourselves forward, but discredits our abilities in the eyes of the west. Many Chinese systems since 90's are state of the art, with no major design blunders. We have explored many new technology areas such as anti-carrier warfare with our own thinking.
Our consumer technology is broad but our market leading ability is weak. In other words we can make everything--including passenger aircraft--but they wouldn't sell. This is the area where we need the most foreign participation, since many "soft" skills are needed in consumer products.
3. On one hand they claim to be peacefull, and on the other they maintain a huge army, where it should be abundantly clear that nobody really want to invade China - who would want to add the chinese problems to their own??
This question is quite hypocritical. Why do European countries even maintain any army at all? Why does USA spend $400 billion a year? Every country will build a defense force to project its interests as well as the image of itself.
4. They make great claims for their army, yet the record the last 100 years is slightly less than impressive.
The record of People's Republic of China is we never lost a war, and in fact succeeded under adverse conditions. In Korea we advanced hundreds of kilometers against overwhelming firepower, and a very large UN army when counting South Koreans. We soundly beat India near *their* side of the Himalayas. We blungeoned Vietnam many times in the 70's and 80's, defying their alliance with Soviets.
the PLA is superior on land for these reasons:
- we operate at very high tempo. we don't wait around for all the support to be in place. If we can achieve the mission we do it, then we keep going to maximize combat against the enemy.
- we excel under adverse conditions. We have superior basic training. Our soldiers can tolerate more and do more. We are more mobile in bad terrain. The PLA doesn't give up.
- we have great generals. This point is often missed by the West. Our generals have great intuition about operations. They make good use of terrain. They push hard for results and our soldiers follow them. They took a peasant army half way down the Korean penninsula when PRC was a new born country lacking everything. Today there is great progress at increasing professionalism at all levels of command, while retaining these "peasant army" strengths.
