ICSID’s Investment Mediation Insights webinar series provides practical insights on the growing field of international investment mediation.

For an investment mediation to work, both parties—State or State entity and investor—must come to the table willingly, with animage of panelists open mind, and a readiness to engage. In this installment of Investment Mediation Insights, we consider mediation from the perspective of an investor—as well as that of an investor’s counsel. The subsequent webinar will then discuss mediation from the side of the State, and a State’s legal representation.

To be discussed:

  • Why would an investor choose investment mediation? What are the benefits?
  • When is mediation is a suitable option for resolving differences?
  • How does experience with investment mediation compare to that of arbitration?
  • Are there benefits to mediating even where the process does not result in settlement and the dispute proceeds to arbitration?  
  • At what stage in a dispute should mediation take place with a State party to be successful?
