At Monday's session of the National People's Congress Standing Committee, lawmakers reviewed the draft law on vehicle and vessel taxation for the first time, which sets out provisions for reducing taxes on energy-saving and clean energy-powered vehicles while imposing more taxes on cars with big engines.

The law is expected to improve and standardize the taxation system, following the principles of being fair, eco-friendly and saving energy.

China, having a total of 199 million vehicles, currently only has a regulation on vehicle and vessel tax, that took effect in 2007.
