# International Meeting of Communist and Workers' Parties

The International Meeting of Communist and Workers' Parties (IMCWP) is an annual conference attended by communist and workers' parties from several countries. It originated in 1998 when the Communist Party of Greece (KKE) invited communist and workers' parties to participate in an annual conference where parties could gather to share their experiences and issue a joint declaration. The most recent and 23rd meeting of the IMCWP was held in October 2023 in İzmir and was hosted by the Communist Party of Turkey (TKP). The 24th meeting was scheduled to be held in Lebanon, hosted by the Lebanese Communist Party (LCP) between 25–27 October, but was postponed due to the Israeli invasion of Lebanon.

## Organization

The Working Group (WG) of International Meeting of Communist and Workers' Parties (IMCWP) is composed of Communist Parties throughout the world. The task of the working group is to prepare and organize the International Meetings of Communist and Workers' Parties (IMCWPs).
The meetings are held annually, with participants from all around the globe. Additionally, there are occasionally extraordinary meetings such as the meeting in Damascus in September 2009 on "Solidarity with the heroic struggle of the Palestinian people and the other people in Middle East". In December 2009, the communist and workers' parties agreed to the creation of the International Communist Review, which is published annually in English and Spanish and has a website.
