MOSCOW, March 6 (Xinhua) -- China can achieve sustainable economic development in decades to come, which will also benefit the rest of the world, a Russian scholar has said, voicing his confidence in the country's long-term growth.

China's gross domestic product (GDP) growth target of "more than 6 percent" for 2021 can be surely attained, said Alexander Lomanov, deputy director at the Institute of World Economy and International Relations of the Russian Academy of Sciences.

The GDP target was made out of "caution and political modesty" and there is a consensus that the growth rate is likely to be higher than 6 percent this year, Lomanov told Xinhua recently.

Lomanov was impressed by China's new economic development pattern of "dual circulation," in which the domestic and overseas markets reinforce each other, with the domestic market as the mainstay.

In his view, the transition to the "dual circulation" model is an important stage in the development of China's economic policy.

"It has its own internal logic and the Chinese leadership has stressed the importance of domestic demand for years," he noted.

Lomanov said China has found a way that will drive growth for the coming decades and help the country avoid falling into the so-called "middle-income trap" or stagnation.

"This is important for the outside world. For those who intend to continue constructive cooperation with China, this is an important signal that they can be sure China is a promising partner as well as a reliable one in terms of honoring commitments," he said.

The Russian expert also praised the country's victory in eradicating absolute poverty as one of China's major achievements over the past five years.

"This success, in terms of its significance and historical meaning, goes beyond the scope of one five-year plan," Lomanov said.
