Full coverage: G20 Hangzhou Summit

With Europe also struggling to cope with an economic slowdown, business leaders and experts have a lot of expectations from this G20 summit.

"I think the most important task for the G20 group is to increase employment and promote economic growth. All the countries in the Summit should take responsibility and work together toward that goal," said Emma Marcegaglia, Chairwoman, ENI.

"I hope there will be mutually-beneficial agreements to come out of the Summit, so that Europe and China can invest in each other without any hesitation. That way Europe and China can have closer economic bond."
