Beijing has announced a clampdown on limousine useage for Government officials. The Standard today gives us an idea of the scale of government owned cars in China:

To get some idea of the amazing number of Chinese bureaucrats there are shuffling along in government-owned cars, consider this: maintenance and operation of official limousines in 1999 was taking up 3.6 percent of the national budget and costing 300 billion yuan (HK$287.88 billion). That was nearly three times the 107.64 billion yuan China was admitting to spending on the national defense budget, although of course the unofficial defense budget runs much higher, to about 20 percent of GDP. In the 1990s, the average number of official limousines grew 27 percent a year. Nearly a quarter of all government procurements in 2004 were for limousines for bureaucrats. Probably one out of every two cars you see on a highway in China is operating at government expense.
