When talking about a topic in which people attach great emotions in, it is always good policy to tread carefully. There are always three-sides to a story, his version, her version, and the truth. Even when scholars try to be objective, there will always be an slant that is shaped by one's experiences and education.
The question as posed is very inflammatory to the Chinese while at the same time, would get a strong nod of approval by the expat community that no doubt shares the same exacerbation. The question implies that China has no culture, thereby implying that Chinese people have no culture; therefore all the "uncivilized" behavior in which we see is a natural consequence of such condition. We can then be quite smug with ourselves and our own "civilized" culture.
But if we back up a bit and ask what is culture, then the question becomes as nonsensical as asking if God still exists. For those that believe in God then he exists as He always has and for those who don't believe, He has never existed therefore how can one ask if He still exists.
If by culture the OP is referring to traditional Chinese culture then one would have to define what is traditional culture. For civilizations that have existed as long as China has, it would be impossible for cultures and traditions to remain unchanged throughout. Traditions and cultures change and evolve naturally with each passing generation. To expect the Chinese to adhere to all your notions of what Chinese culture should be would be akin to the Chinese going to London and expecting to see knights in shining Armor jousting in front of the Castle in which they live.
If by culture the OP is referring to "Western" culture, then this is a value judgment. How can one equate Western culture as having culture and non-Western culture as having no culture? This would be like saying White men are men while Black men are not. There is no right or wrong culture, only to what you are accustomed. Indians (not Native Americans) use their bare hands (the left hand) to wipe themselves after a bowel movement (and washes that hand promptly). Westerns might be repulsed by this on the grounds that it is unsanitary and yet how many Indians contract diseases through this "unsanitary" custom vs. those that employ the toilet paper wipe method? We are all shocked and disgusted at the sight of Chinese parents letting children relieve themselves on public sidewalks, but besides being looked-down upon by foreigners, what ill affects does that have on Chinese development and Chinese society.
Chinese people look-down upon Westerners as the "devil" while Westerners look-down upon Chinese as "uncivilized" people waiting for someone to civilize them. This is the way it always has been and always will be if we keep deciding to be intolerant to one another. It is disappointing although not surprising to see so many people who choose to travel and experience different countries so willingly yet aren't will to accept different cultures; this goes to all nationalities (although I do find the Chinese and Americans are the most flagrant offenders).
It is not my intent start a flaming war but instead, just providing some quick perspective on the matter.
The weather's changing, time to break out the winter clothes.
Stay warm! Cheers~
