Prime Minister Dr Mahathir Mohamad has a responsibility to the Malaysian people to make an executive decision on the status of the East Coast Rail Link (ECRL) project, said a Beijing-based political commentator.<br /><br />In a commentary published in Channel News Asia today, Tom McGregor pointed out that the flip-flop is derailing Malaysia's credibility.<br /><br />“Either he (Mahathir) supports the ECRL or stands opposed to it, and leads his government to implement that decision.<br /><br />“To keep an external partner guessing and leave CCCC (the Beijing-owned China Communications Construction Co Ltd) in a state of animated suspense violates all sense of diplomatic decorum and kills off any remaining business confidence other countries might have in dealing with Malaysia,” he added.
