Han Jae-jin, a researcher with South Korea's Hyundai Research Institute, said further transformation of government functions, one of the key issues to be discussed at the plenum, would send positive signals to the world.

He said the reform would attract more overseas investment to China and push forward the economic advance of China's neighboring countries, even the world.

Expectations of a "spill-over effect" from China's reform are high across the world.

Doris Fischer, a professor at Warzburg University, hoped the plenum would give more space to the private sector, including overseas corporations, and pay more attention to innovation.

Do Tien Sam, director of the Institute of Chinese Studies under the Vietnam Academy of Social Sciences, said China's steady development would bring development opportunities to the region and the world.

Argentine economist Matias Carugati expected more growth space for the global economy as changes to Chinese government functions brought investment opportunities and created a better institutional environment.

China's reform also served as an inspiration for other countries. "...Certain aspects of China's cautious approach to economic reforms ... might actually prove an object lesson to other countries," said an opinion piece by Eswar Prasad on the website of Britain's Financial Times.

China's success in mutually promoting reform, development and stability has set a good example and provided valuable experience for other countries, some scholars say.

As reform becomes an irresistible trend, China will unswervingly adhere to the reform and opening up policy, which will also provide hope and opportunities for other countries.
