The UK parliament resoundingly rejected Prime Minister Theresa May's Brexit divorce deal on Tuesday, prompting expressions of concern among EU leaders who say they are stepping up emergency planning for a possible 'hard Brexit'.
Kurz said the EU could help to further clarify aspects of the withdrawal deal but that Britain needed to take the initiative and state clearly what it wants.
"Regarding the future relations ... there is of course the possibility of further defining certain points if this helps to avoid a hard Brexit scenario", Kurz told a news conference in Vienna.
"The main target is to avoid a hard Brexit. If we need more time to reach that, then we should consider that option," Kurz said, echoing a proposal by German Economy Minister Peter Altmaier.
Britain is due to leave the EU on March 29, though speculation has increased that the deadline may have to be extended to allow May more time to overcome deep divisions in her Conservative Party and in the UK parliament.
