Hi Reshma
Having imbibed legal education internationally concentrated in the field of international business predominantly international business arbitration, I think I can help effectively. Any corporation be in indian or otherwise, when enters into a business transaction (contract) with a foreign company can sure select arbitration as selective mode of its contractual dispute resolution. In your case, the foreign company is a Hongkong company. In an international business contract, if the parties choose to arbitrate their disputes, then they can select any forum around the world to arbitrate their issues whether institutional or adhoc. Supreme Courts around the world have mandated an arbitral tribunal or institution to entertain a dispute before it. After all, they get money. Now, thanks to the New York convention, an arbitral award that a third country makes, can be enforced in the defendant's country.
In your case, the parties can sure, by mutual consent, choose Hongkong as their arbitration venue with a suitable forum entertaining the arbitraiton. However, it is not essential at all that the substantive law that shall apply to such arbitration shall be HK law. It can be law of any third country. If it is a contract for international sale of goods, then an international law can apply, i.e. CISG. However, in practice, you should never choose a forum of the other party. If the other party is so adament then you can choose a third neutral country as your venue and forum of arbitration where the procedural law governing the arbitration will be of that respective country and substantive law applicable to such arbitration shall be as the parties might agree to.
Should you have any more questions, kindly let me know.
