On 26 November 2013, the Cuban Interests Section (the “Section”) in Washington, DC,  which functions as Cuba’s de facto embassy in the US, announced the discontinuation of  all consular services except for humanitarian cases and other limited circumstances,  claiming that the Section was unable to find a new banking services provider in the US.  On 12 July 2013, the Section’s previous bank, M&T Bank, informed the Section that it  would no longer provide banking services to foreign missions. The Section has cited US  sanctions against Cuba as the reason for its difficulties and asserted that, although the US  Department of State has made “numerous efforts” to assist the Section, the US  government has not complied with a legal duty to accord full facilities for the performance  of the functions of the consular office. On 6 December 2013, according to the Section,  M&T Bank extended the deadline for the Section to close its accounts, allowing the Section to resume full consular services until 1 March 2014.
