Query: What year did Somali authorities rejoin the Universal Postal Union?
Context: Phase I will see the reconstruction of the postal headquarters and General Post Office (GPO), as well as the establishment of 16 branch offices in the capital and 17 in regional bases. As of March 2012, the Somali authorities have re-established Somalia's membership with the Universal Postal Union (UPU), and taken part once again in the Union's affairs. They have also rehabilitated the GPO in Mogadishu, and appointed an official Postal Consultant to provide professional advice on the renovations.
