Remedy if international arbitration proceedings have been stayed

Our company (France) has entered into an agreement with an Indian company to manufacture and market medical products. It is a joint venture. We are manufacturing and selling the products in India. We entered into this JD considering various sops provided by the State government. Now, the State government has challenged the sops provided and have not refunded the sops in crores. Based on the protocols between India and Korea related to trade and commerce, we have moved international arbitration against State government. The State has moved the high court to bring a stay on arbitration proceedings. The stand taken by State is that since there are clauses related to invoking arbitration and local jurisdictional courts, the High Court should not allow our company at Korea to invoke the clauses in international protocol to seek remedy. We need a proper advise on this and a barrister to immediately initiate remedial measures.
