In a bid to fight global warming, Japan on Thursday promised to boost its assistance for developing nations to ¥1.3 trillion a year by 2020.

The announcement apparently is aimed at securing a better negotiating position for Tokyo in the global climate talks set to kick off in Paris on Monday.

The ¥1.3 trillion package, which will include projects by both the private and public sectors, is up about 30 percent from the actual budgets allocated for fiscal 2014.
