China has placed innovation and global coordination top on the agenda to reinvigorate the world economy in a post-crisis era at the just-concluded Group of 20 (G20) summit, according to an Argentine expert.

In a recent interview with Xinhua, Jorge Castro, director of the Institute of Strategic Planning in Buenos Aires said the summit was "an event of extraordinary importance and China placed atop the agenda the need to establish coordinated policies across the world."

Castro added that this mechanism could be a platform for governance for the next few years. "The path is to take action by driving innovation," he said, adding that China wanted the G20 to be a place for action, not only conversation.

"There is no way for a country to escape from stagnation in a global community without a common effort," Castro said.

The future of the G20 is of particular importance to Argentina, which will host the 2018 G20 summit, after Germany does so in 2017.

"Argentina will play an important role as the host country in 2018," said Castro.

The 2016 G20 summit concluded on Monday with the adoption of a statement outlining the group's direction and development goals, and with the Hangzhou Consensus on facilitating global economic growth by adopting comprehensive, open, innovative and inclusive long-term measures.
