Sox - relavance to indian companies

I ve learnt about SOX in CA FInal AUdit . I ve learnt about all the Major Provisions and Sox 404 and Information Technology related controls and about PCAOB rules and its requirements from Auditors . But the confusion is all those are only US Companies as Sarbanes Oxley s Act is a act applicable and in U.S. and so the companies in U.S. are covered under this Act .

In what all manners will all such provisions of SOX be applicable to Indian Companies ?
