Algeria’s decision to terminate the Friendship and Cooperation Treaty with Spain could have significant repercussions on various fronts, particularly energy supplies. Spain relies on Algeria for over a quarter of its natural gas imports, raising concerns over future gas pricing and availability. The diplomatic rift also threatens cooperation in crucial areas such as security, immigration, and counter-terrorism. Experts suggest Algeria’s frustration stems from perceived disregard during Spain’s shift in stance on Western Sahara, marking a serious diplomatic crisis with unpredictable consequences for both countries’ economic and political relations.
