BEIJING, March 8 -- China's busy diplomacy has been"worthwhile and fruitful" in the past years, Foreign Minister Wang Yi said Tuesday on the sidelines of the national legislative session.

He made the remarks when responding to a question submitted online by Chinese netizens on diplomacy's impacts on the lives of ordinary people.

"Many problems in the world cannot be resolved without China's participation," Wang said, citing 20 overseas visits of President Xi Jinping around the globe in the last three years.

China's busy diplomacy has benefited the people's livelihood, Wang said.

Referring to an example, Wang said the Yiwu-Teheran railway started operation four days after Xi's visit to Iran in January, serving as a cost-effective channel of transportation for over70,000 businesses in Yiwu and creating more opportunities and better profits for them.

China's diplomacy will get busier and Chinese people can expect more benefits, Wang said.

It was the first time that an online question from ordinary people was raised in such a major press conference during the annual session of the National People's Congress.
