The Communist Party of China has achieved a great deal during its efforts to reform the nation's political structure and will continue with the work, based upon China's own conditions, rather than by copying others' models, said a senior spokesman.

Tuo Zhen, spokesman for the 19th CPC National Congress that will begin on Wednesday, made the remarks at a news conference on Tuesday afternoon in Beijing's Great Hall of the People.

He said the reform of the nation's political structure has remained a key topic on the Party's agenda since China adopted its reform and opening-up policy nearly 40 years ago.

"The Third Plenary Session of the 18th CPC Central Committee meted out roadmaps for the ongoing comprehensive reforms, including 60 tasks for political structure reform," Tuo said.

The Fourth Plenary Session published 190 measures to boost the rule of law, and the Sixth Plenary Session arranged for new efforts to be made to improve the management of Party members, Tuo told reporters.

"Thanks to all of these steps and previous measures, the reform of the political structure has had historic accomplishments and has laid a solid foundation for deepening reforms in other sectors," he said.

The spokesman noted that reform of the political structure "can't be fulfilled overnight" and that China will not "copy or duplicate others' models" because it has a unique culture, tradition, history, and conditions.

"Therefore we must walk along the development path that suits our own characteristics," he said.

Attendees of the 19th CPC National Congress will make comprehensive plans for reforms of the political structure and other systems in accordance with the Party's experience and unsolved problems, he said. The Party will firmly push forward its endeavors to improve socialism with Chinese characteristics and the government's governance capabilities, said Tuo.
