John has been engaged in an international transaction, regulatory and dispute resolution practice since 1979. He has extensive experience in the Middle East where he has been resident since 1980, including in Saudi Arabia for a period of ten years. He has also practiced throughout Asia and Europe since the mid-1980’s.

John's commercial practice concentrates on international commercial transactions, including the negotiation of manufacturing strategic alliances in the aerospace, petrochemical and high-technology industries in the Middle East, Asia and Europe. He also advises international and Middle Eastern clients on matters relating to the establishment of joint ventures, distribution arrangements, and the regulation of business activities, including the satisfaction of foreign investment, local law and fiscal requirements.

He has represented numerous international defense and technology companies in connection with governmental sales whether on a direct or a foreign military sales basis. That representation includes advising on the equipment and service provision aspects of the transaction, advising on local and U.S. regulatory issues, and assisting in the structuring and satisfaction of offset and local manufacturing requirements. This experience includes commercial and military aircraft, security systems and technology and land systems. He has also advised service providers in the defense and security industry segments.

John also has extensive energy experience, including the negotiation of upstream transactions and advising service and equipment supply companies relating to the conduct of their operations in the Middle East and elsewhere. In this regard, he has advised both IOC’s and service companies relating to transactions in both the State of Iraq and Kurdistan. Prior to the unification of Yemen, he acted on behalf of both the Peoples’ Democratic Republic of Yemen and the Yemen Arab Republic in connection with the negotiation of drilling and production rights with a foreign group led by U.S. and European oil companies. John has also advised foreign contractors and operators relating to the development, construction and operation of energy facilities in the region, including the establishment of concessionary greenfield petrochemical joint ventures and technology license transactions.

John has also represented many clients in connection with international dispute resolution, whether conducted locally in the Middle East or pursuant to foreign arbitration. Subsequent to the 1991 Gulf War, John led a multidisciplinary team of over 150 international and Kuwaiti professionals (attorneys, accountants and engineers) that advised, prepared and resolved approximately $100 billion of claims for the Government of Kuwait against Iraq relating to the invasion and occupation of Kuwait. The claims were argued before the United Nations Compensation Commission in Geneva. John also represented Kuwait and Saudi Arabia before that forum in addressing each country’s environmental claims against Iraq arising from the first Gulf War.

John advises international and local companies regularly on compliance matters arising from U.S. and local regulations that apply to the conduct of their international operations. Those activities include the conduct of numerous investigations in the Middle East, Europe and Asia to ensure compliance with applicable U.S., international and local regulations, including the U.S. Foreign Corrupt Practices Act and Antiboycott Regulations, as well as applicable sanctions and export regimes. He speaks frequently on those topics and assists companies in developing their compliance programs, training their personnel relating to the same, and conducting both due diligence and investigations to ensure compliance. He has conducted numerous investigations relating to these and other corporate and regulatory compliance matters in the United States, Europe, the Middle East, Asia and South America.

John has authored numerous articles and spoken at a variety of conferences on matters relating to international business and U.S. trade regulatory issues.
