According to an update from the OECD, Belize and Cameroon deposited their instrument of ratification for the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI) on 7 April and 21 April 2022, respectively. Based on the dates of deposit, the MLI will enter into force for Belize and Cameroon on 1 August 2022, although its entry into force for the countries' respective covered agreements (tax treaties) will depend on the ratification of the MLI by the counterparty to a particular covered agreement.

The MLI will generally enter into force for a particular covered agreement on the first day of the month following a three-month period after both parties to the covered agreement have deposited their ratification instrument. Once in force, the provisions of the MLI will generally apply for a covered agreement from 1 January of the year following its entry into force in respect of withholding taxes, and for all other taxes with respect to taxable periods beginning on or after the expiration of a 6-month period following the date of entry into force.
