Under pressure to jolt the lethargic world economy back to life, leaders of G-20 nations on Sunday finalized a plan to boost global GDP by more than $2 trillion over five years.

World leaders on Sunday prepared to release details of a plan aimed at injecting life into the world’s listless economy, with infrastructure investment and the lowering of trade barriers flagged as key components of the initiative.

Australia’s prime minister vowed that world leaders would deliver on an initiative to add $2 trillion to global GDP, promising freer trade and more investment in infrastructure as heads of the 20 largest economies began cementing plans to drag sagging growth out of the doldrums.
