Wen said Beijing can meet its 2009 growth target of 8%, despite skepticism by private sector economists, who expect as little as 5%. That would be the strongest of any major country but could lead to more waves of job cuts.
"I really believe we will be able to walk out of the shadow of the financial crisis at an early date," he said. "After this trial, I believe the Chinese economy will show greater vitality."
The premier promised to focus on job creation and give more help to smaller companies, which he said generate 90% of Chinese new employment.
"We will pay all attention possible to this issue and we will never overlook this issue," he said.
Wen said Beijing wants the London summit to focus on the plight of poor countries.
"We must see to it that we show concern for developing countries, and help developing countries — the least-developed ones in particular — become an important topic on the agenda," he said.
