Coordinating Committee for the Refoundation of the Fourth International
The Coordinating Committee for the Refoundation of the Fourth International (CRFI) is a Trotskyist international organisation. Its name in Spanish is Coordinadora por la Refundación de la Cuarta Internacional. It was formed in 2004 at a conference in Buenos Aires called by the Movement for the Refoundation of the Fourth International. It has members in South America, Western Europe and the Middle East. The committee has nine members, two each from Italy and Brazil, and one each from Uruguay, Argentina, the US, Greece, and Israel/Palestine. They include Jorge Altamira, Savas Mihail Matsas, Sungur Savran and Marco Ferrando.
The Argentianian PO is the largest section of the CRFI and as such drew its international co-thinkers into the new tendency from other countries in Latin America. However the Workers Revolutionary Party of Greece and the International Trotskyist Opposition had different roots from the PO and its allies. The fusion of these groups provides the CRFI with small but real bases in both Greece and Italy.
It held a conference of worker-militants in the European and Mediterranean region in Athens in June 2013.  It held a further meeting of its International Committee in December 2013.  It held a second conference of worker-militants in the European and Mediterranean region in Athens in March 2014.

- Workers' Party (Partido Obrero, PO) in Argentina.
