Chinese economy has strong momentum and resilience, and market entities are highly resilient against risks, a senior economic official said Saturday, citing the "unprecedented" rise in economic aggregate in 2021.

China's gross domestic product reached 114.4 trillion yuan in 2021, and the rise of the economic aggregate of 13 trillion yuan or $3 trillion in a single year was unprecedented in the history of China and the world, said He Lifeng, head of the National Development and Reform Commission.

Despite difficulties and challenges as well as destabilizing factors, China has the conditions, capability and confidence to achieve this year's targets and tasks, the official said, adding that this year's economic growth target of around 5.5% is achievable through hard work.

The "two sessions," the annual meetings of the National People's Congress and the National Committee of the Chinese People's Political Consultative Conference, started on Friday and will run through March 11.
