BEIJING, March 4 -- China will continue to push forward the implementation of law-based taxation, a spokesperson for the nation's top legislature said Friday.

Fu Ying, spokeswoman for the Fourth Session of the 12th National People's Congress (NPC), made the remarks at a press conference prior to the opening of the session slated for Saturday.

"We have seen marked progress in law-based taxation," Fu said.

The Legislation Law revision approved last year mandates that all taxes be imposed through legislation, and the legislature has included law-based taxation into its work agenda, Fu said, citing taxes of environmental protection, resources and tariff, as well as value-added tax.

China has formed its time frame and blueprint for the implementation of law-based taxation, Fu said, noting that she hopes the lawmaking of environmental protection tax will be passed this year.

In addition, draft laws on tobacco leaf and vessel tonnage taxes are likely to be submitted to the NPC Standing Committee this year, Fu said.
