Prime Minister Taro Aso pledged Thursday that the government will try to create 1.4 million to 2 million new jobs in the next three years by spurring ¥40 trillion to ¥60 trillion in new demand.

In the long haul, Aso said he believes the economy will see real gross domestic product grow by ¥120 trillion and new jobs by 4 million by 2020.

The new pledge came as Aso was scheduled to announce Friday a fiscal 2009 supplementary budget worth ¥15 trillion, which would be the largest extra budget ever.
