Comoros-a former French colony whose currency is linked to the euro-will retain strong ties with France, its main bilateral aid donor and trading partner. Although Comoros will continue routinely to condemn France's "occupation" of Mayotte (the fourth island in the archipelago, which is a French overseas department), relations between the two countries will remain strong, underpinned by France's importance for Comorian economic policy (the French Treasury guarantees the Comorian franc) and the recently renewed military co-operation pact between the two countries. Under Mr Sambi, Comoros has pursued an open-door foreign policy, seemingly cultivating ties with any country that has been willing to provide it with aid or investment. As a result, it is one of the few countries that have cordial relations with both the US and Iran. Relations with Iran have raised some alarm, especially as Iranian military personnel reportedly form part of Mr Sambi's personal security detail. However, this has not alienated the country's Western allies, which seem keen to retain their influence in Comoros. (The US, for example, has continued to provide Comoros with preferential access to its market under the African Growth and Opportunities Act since mid-2008.) Mr Sambi's policy has also led to growing commercial and diplomatic ties with Qatar, Dubai, Kuwait and China. As with most aspects of the policy agenda, foreign policy is expected to remain largely unchanged under Mr Dhoinine. Ties with the Middle East in particular, are likely to stay strong, assuming that the recent generous pledges of aid and investment from the Middle East are upheld. Comoros is expected to remain on good terms with other countries in the region, underpinned in part by its membership of the African Union and the 19-member Common Market for Eastern and Southern Africa (COMESA). The threat from Islamic fundamentalist groups appears limited; to date, there have been no extreme Islamist threats and no known establishment of terrorist cells in Comoros.
