Finance chiefs from the 20 largest economies said on Sunday they are close to reaching their goal of boosting world GDP by more than $2 trillion over the next five years, and will focus on infrastructure investment to help reach the target.

Australian Treasurer Joe Hockey, who hosted the Group of 20 meeting in the northern Australian city of Cairns, said the G-20 finance ministers and central bankers had agreed to more than 900 policy initiatives to meet the goal they set in February during a gathering in Sydney.
