Private car ownership is increasing at an annual rate of 15%, although it is still uncommon because of government policies which make car ownership expensive, such as taxes and toll roads. Private highway driving is becoming more common, being almost nonexistent ten years ago.

Domestic air travel has increased significantly, but remains too expensive for most. Long distance transportation is dominated by railways and charter bus systems. Railways are the vital carrier in China; they are monopolized by the state, divided into various railway bureaus in different regions.

Numerous cities are also constructing subways. Hong Kong has one of the most developed transport systems in the world. Shanghai has a Maglev rail line connecting Shanghai's urban area to Pudong International Airport.
