(a) Of course more quickly in China.  Raising funding for public facilities is always a headache, anywhere, and in a democratic society the process often takes forever.  If fees are properly charged, those facilities not expected to yield sufficient income will be ignored, but those expecting a good return will be constructed promptly.

(b) The quality and maintenance of public facilities tend to vary far more greatly in China than in the U.S.  Facilities loaded with tourists, hence enjoying high incomes, are observed to keep investing to maintain the facilities, along with adding new features.  Facilities with few tourists are observed of not even watering the plants.  In the U.S., public facilities are funded by the government, which tend to follow some established formulae of funding year after year.

(c) There are of course more tourist guides serving tourist attractions in China.  They get kick-backs from tourist attractions, usually getting a cut from the admission fees.
