  • We regularly invoke investor-state dispute resolution instruments, proceedings and negotiations between foreign investors and host states and their governments under applicable bilateral investment treaties, normally pursued in parallel to domestic proceedings, to prevent, settle amicably or otherwise resolve high-value disputes in cases where domestic institutions and instruments, including national courts, fail to remedy an injustice caused to foreign investors by arbitrary, unfair or discriminatory governmental actions, including a direct or indirect expropriation of investments by host states.
  • We combine our broad experience and local expertise to help our Clients find efficient solutions for a wide range of regulatory issues and protect their long-term interests.
  • We often represent companies in litigation involving registration of their products and services, export-import and foreign exchange restrictions.
