BERLIN, May 18 (Reuters) - German Finance Minister Wolfgang Schaeuble does not want any debt relief for Greece until 2018, thereby avoiding a parliamentary decision on such a move before a federal election expected next autumn, business daily Handelsblatt reported.

Citing a letter to the parliamentary budget committee it had seen, Handelsblatt reported on Wednesday that Schaeuble's ministry had signalled a willingness to ease Greece's debt burden in a concession to the International Monetary Fund.

"These measures would be contingent on full implementation of the [Greek reform] program by 2018," Handelsblatt quoted the ministry as saying in the letter.
