Russians paying Indon leaders to grab Indosat

It is reported in the media that a Russian tycoon, Mikhail Fridman of the Alfa Group, is paying Indonesian leaders to wrestle control of Temasek owned Indosat from Singapore. And the methods used by Altimo, the company owned by Fridman, other than bribery, or they called it gifts, include a smear campaign to tarnish the reputation of ST Telemedia. Project Indosat, as the covert operation is called and reported in Indonesian media, is denied by everyone who has been named to be involved. It is a public secret that even the top Indonesian leaders are alleged to have known of its existence. If it can be proven, that taking money, or bribes or call it corruption in this case, would Singapore be able to use the newly inked Extradition Treaty to bring a few of them to our courts for a trial?
