The government and the ruling parties will draw up additional economic measures that could cost as much as ¥20 trillion to help lift the economy out of recession, sources said Sunday.

The government and the Liberal Democratic Party and New Komeito reportedly hope to compile the fresh stimulus steps and announce the plan ahead of a summit of the Group of 20 economies in London on April 2 and the release of corporate annual earnings reports through March.

Three economic measures have already been adopted between last August and December.
