The United States ambassador to Mozambique has saluted an anti-piracy agreement signed between South Africa and Mozambique last week which presages an accord with Tanzania. South Africa's defence minister Lindiwe Sisulu signed a memorandum of understanding with her Mozambican counterpart Filipe Jacinto Nyusi. The two countries applauded successful patrolling activities off the central Mozambican coast and decided to involve Tanzania - north of Mozambique - in their activities.
