Having mediated negotiations that led to the presidential poll in Mauritania, Mr Wade will have a strong relationship with Senegal's northern neighbour. The fragile administration of Guinea-Bissau's president, Malam Bacai Sanhá, may not prove willing-or able-to assist Senegal's campaign against the Casamance separatists, who reportedly draw support from kinsmen over the border. Guinea's return to civilian rule will improve regional stability. Support from Senegal's main trading partners in the EU-notably France-will remain strong. Relations with China have flourished since the start of diplomatic ties in 2005. Burgeoning commercial ties with Iran have been severed following the discovery of an illegal arms shipment to The Gambia and the intensification of Casamance rebel violence using weapons originating from Iran, despite the promise of more investment.
