The 2017 edition was withdrawn in March 2025 and replaced by the 2025 edition. This brochure on ‘Promoting Maritime Treaty Ratification’ was developed by ICS and the Comité Maritime International (CMI), as part of an ongoing joint campaign highlighting the need for governments to ratify and implement maritime conventions adopted by the International Maritime Organization (IMO), the International Labour Organization (ILO) and other United Nations bodies that impact on shipping.
