The nation's biggest business lobby is set to resume recommending for the first time in five years that its member companies make political donations, in an effort to strengthen ties with Prime Minister Shinzo Abe's administration to gain a bigger say in policy.

Keidanren will urge its around 1,300 corporate members to make political contributions, Sadayuki Sakakibara, chairman of the lobby group, said Monday at a news conference.

The group will make an official decision on the matter Thursday.
