ICSID's main objective is to provide facilities for conciliation and arbitration of investment disputes between foreign investors and host states, thereby promoting the flow of foreign investment and economic development.

ICSID was established in 1965 under the Convention on the Settlement of Investment Disputes between States and Nationals of Other States.

ICSID is administered by the World Bank, which provides administrative and financial support for the institution.

ICSID's jurisdiction is limited to investment disputes between foreign investors and host states, excluding disputes between private parties, labor disputes, and intellectual property disputes.

ICSID offers three main methods of dispute resolution: conciliation, arbitration, and mediation. Conciliation involves a neutral third party facilitating negotiations between the disputing parties, while arbitration involves a tribunal making a binding decision on the dispute. Mediation is a less formal process where a neutral third party assists the parties in reaching a mutually acceptable settlement.

The ICSID Secretariat is responsible for providing administrative and logistical support for ICSID proceedings, including arranging hearings, managing case files, and communicating with the parties involved in the dispute.

The ICSID Convention is a treaty that establishes ICSID and sets out its rules and procedures for the conciliation and arbitration of investment disputes. It provides the legal framework for ICSID's operations and is binding on all ICSID member states.

ICSID has over 150 member states, representing a wide range of countries from different regions of the world.

ICSID awards are binding on the disputing parties, can be enforced in over 150 countries that have signed the ICSID Convention, and set precedents for future investment disputes, influencing the development of international investment law.

ICSID has been criticized for being biased in favor of foreign investors, being too expensive for developing countries to participate in, and lacking transparency and accountability in its proceedings.

Recent developments in ICSID arbitration include increased use of virtual hearings and electronic filing to improve efficiency, expansion of ICSID's jurisdiction to include environmental disputes, and adoption of new rules to streamline the arbitration process and reduce costs.

The ICSID Administrative Council is responsible for overseeing the administration and finances of ICSID, appointing the Secretary-General of ICSID, and adopting the ICSID rules of procedure.

The ICSID Panel of Arbitrators is a list of individuals who are qualified to serve as arbitrators in ICSID proceedings. The Panel is composed of independent experts in international law and arbitration, and arbitrators are selected from the Panel for each ICSID case.

The ICSID Secretary-General is responsible for managing the day-to-day operations of ICSID, representing ICSID in external relations, and appointing arbitrators and conciliators for ICSID proceedings.

ICSID is funded through a combination of contributions from member states, fees paid by disputing parties, and investment income.
