Explanation:

Formed in 1999, the G-20 has a mandate to promote global economic growth, international trade, and regulation of financial markets. Because the G-20 is a forum, not a legislative body, its agreements and decisions have no legal impact, but they do influence countries' policies and global cooperation.
The objectives of the G20 are: a) Policy coordination between its members in order to achieve global economic stability, sustainable growth; b) To promote financial regulations that reduce risks and prevent future financial crises; and c) To create a new international financial architecture.
