BEIJING -- Relevant parties should not put disputes, including territorial controversies, into the G7 summit, Chinese Foreign Minister Wang Yi said Friday at a joint press briefing following talks with visiting German Foreign Minister Frank-Walter Steinmeier.

If some countries deliberately put historical issues or even disputes over territorial sovereignty into the G7 summit, it will not only be helpless for resolving the issues, but also be harmful to regional stability, which is obviously unacceptable, Wang said.

G7 summit will be held in Japan in May.

"We hope the G7 summit will focus on the topics of economy and development, which are the biggest concern all around the world, just as G20 does," he said.

Answering questions about the relations between G7 and G20, Wang said the G20 comprises major developed and developing countries, which account for more than 80 percent of global economic output and international trade.

"This indicates that G20 is more representative for the common aspiration and consensus of the international community," Wang said, adding that G20 has become the most important platform for global economic governance and cooperation.

As the host of this year's G20 summit, China will cooperate with other G20 members, including Germany, to find solutions to major problems of the world economy, said Wang.

This year's G20 Leaders Summit will be held in September in Hangzhou, a popular tourist city and capital of east China's Zhejiang province.

Invited by Wang, Steinmeier is paying a visit to China from Friday to Sunday. The two ministers co-chaired the second session of Chinese-German strategic dialog on diplomatic and security affairs on Friday.
