Explanation:

CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between governments. Its aim is to ensure that international trade in specimens of wild  animals and plants does not threaten their survival. Appendices I, II and III to the Convention are lists of species afforded different levels or types of protection from over-exploitation. Appendix I includes species threatened with extinction. Trade in specimens of these species is permitted only in exceptional circumstances. Appendix II includes species not necessarily threatened with extinction, but in which trade must be controlled in order to avoid utilization incompatible with their survival. Appendix III contains species that are protected in at least one country, which has asked other CITES Parties for assistance in controlling the trade. CITES is legally binding on the Parties - in other words they have to implement the Convention.
Resolution of Disputes- Any dispute arising between two or more Parties with respect to the interpretation or application of the provisions of the present Convention shall be subject to negotiation between the Parties involved in the dispute. If the dispute can not be resolved through negotiation, the Parties may, by mutual consent, submit the dispute to arbitration, in particular that of the Permanent Court of Arbitration at The Hague, and the Parties submitting the dispute shall be bound by the arbitral decision. The Permanent Court of Arbitration (PCA) is an international organization. The Hague, the Netherlands. It is not a court, does not have permanent judges, and should not be confused with the International Court of , a separate institution also in the Peace Palace. The PCA is a permanent bureaucracy that assists temporary tribunals to resolve disputes among states (and similar entities), intergovernmental organizations, or even private parties arising out of international agreements.
