America's eyes what "the Chinese are" the most expensive?

U.S. defense secretary yesterday to visit Beijing, reporters on the plane, he first concern is invisible fighter, he came to China's main purpose is to??????? I think he to the main purpose of China, is when "detective", not only want to make sure that the purpose of China's development of military technology, but also find out whether China has developed stealth fighter, "aircraft carrier killer" anti-ship ballistic missile range is reached 3200 kilometers. America in the eyes of "Chinese goods" what the most expensive? Stealth fighter planes. Things for your notes, can be made invisible fighter, the world's only the United States, also is the F-22, now suddenly appeared annihilates-20 of the pictures, you can let the United States said to sleep? If plus the legendary "aircraft carrier killer", with the economy in bad because and had to cut military, defense secretary Robert gates is more agonizing. He came to China, in addition to restart the military exchanges between China and the United States, more important is when "detective" to China's military modernization ground a false or true, to sensitive ErBao to visit, to look at China's military actually have much stronger, is for American super position pose a challenge. His trip to China, and will be of U.S. policy toward China and the United States military adjustment, have great influence. The problem is the "detective" gates can ground to China's military modernization situation? Until now, the military and not to dispel the park in chengdu's invisible fighter what is going on. According to the American thinking, China's military technology is invisible, China's military strategy is invisible, this is most desperately. In fact, China is already shows that Chinese development military technology is not like America seek hegemony of the world, but more effectively maintain their own core interests, and defend their countries. But the United States does not believe, must want to make clear, like gates in the plane of the said, the military potential of China is "put our troops at risk", he wants to make clear that China is invisible and combat opportunity won't begin in 2025 equipment for the troops. But I think, he is not satisfied, China can own vicious military secrets to give you the gates?
