Rival parties, after nearly three weeks of parliamentary impasse, agreed Thursday to pass an extra budget plan at the National Assembly's regular session later this week.

Floor leaders of the ruling Saenuri Party and the opposition New Politics Alliance for Democracy agreed to pass the 11.2 trillion-won ($10.3 billion) supplementary budget plan through the regular session on Friday.

The government submitted the budget plan to the parliament for approval on July 6 to boost the troubled economy, with policymakers initially expressing hope it would be passed by July 20.

Rival parties, however, have failed to see eye to eye on the budget's size, raising worries that it may not be passed by the end of this month. (Yonhap)
