The Middle East. Trade tensions. Iran’s nuclear program. Venezuela’s power struggle. Civil wars in Syria and Yemen. Familiar flash points such as these got plenty of airtime at the U.N. General Assembly’s big annual gathering this week. But some leaders used their time on the world stage to highlight international conflicts and disputes that don’t usually command the same global attention.A look at some of the less-discussed controversies trying to be heard: NAGORNO-KARABAKH Turkish President Tayyip Erdogan landed one of the coveted first few speaking slots, and he devoted a bit of his wide-ranging speech to a clash in the Caucasus: a standoff between Armenia and Azerbaijan over the Nagorno-Karabakh region. The mountainous, ethnic Armenian area of about 150,000 people is recognized as part of Azerbaijan in UN Security Council resolutions dating to the 1990s. But Nagorno-Karabakh and some neighboring districts have been under the control of local ethnic Armenian forces, backed by Armenia, since a six-year separatist war ended in 1994. Both Azerbaijan and Turkey have closed their borders with Armenia because of the conflict, cutting trade and leaving Armenia with direct land access only to Georgia and Iran. Russia, the U.S. and France have co-chaired the so-called Minsk Group of the Organization for Security and Cooperation in Europe, attempting to broker an end to the Nagorno-Karabakh conflict. In speeches and rebuttals at the General Assembly, Armenia and Azerbaijan accused one another of misstating history, disrespecting human rights and standing in the way of a settlement. NORTH MACEDONIA UN Secretary-General Antonio Guterres’ “state of the world” address was largely a grim one , but he pointed to a few matters moving “in promising directions” – among them relations between Greece and the new Republic of North Macedonia. Greece and what the UN cumbersomely used to call the “Former Yugoslav Republic of Macedonia” sparred for nearly three decades over the latter’s name. It was adopted when the nation, which has a current population of about 2.1 million, declared independence from the former Yugoslavia in 1991. Greece said the use of “Macedonia” implied territorial claims on its own northern province of the same name and its ancient Greek heritage, not least as the birthplace of ancient warrior king Alexander the Great. Athens blocked its Balkan neighbor’s path to NATO and EU membership over the nomenclature clash. It became “infamous as a difficult and irresolvable problem,” in the words of now-North Macedonian Prime Minister Zoran Zaev. Repeated rounds of U.N.-mediated negotiations proved fruitless until June 2018, when the Skopje government agreed to change the country’s name to North Macedonia. The switch took effect this February. European Council President Donald Tusk said this month that North Macedonia is now ready to start EU membership talks. It expects to become the 30th NATO member soon. The deal has been contentious within both countries, though, with critics accusing their governments of giving up too much. Regardless, North Macedonia’s prime minister highlighted it with pride from the world’s premier diplomatic podium. “We can see nothing but benefits from settling the difference,” Zaev said, calling it “an example for overcoming difficult deadlocks worldwide.” Greek Prime Minister Kyriakos Mitsotakis didn’t dilate on the deal, saying only that his country supports EU bids by all the western Balkan countries if they respect their obligations to the EU and their neighbors. WESTERN SAHARA A mostly desert expanse along the northwest coast of Africa, Western Sahara has been a center of friction between Morocco and Algeria for almost half a century. Morocco annexed the phosphate- and fishing-rich former Spanish colony in 1975, then fought the Algerian-backed Polisario Front independence movement until 1991, when the UN brokered a cease-fire and established a peacekeeping mission to monitor the truce and facilitate a referendum on the territory’s future. The vote has never happened. Morocco has proposed wide-ranging autonomy for Western Sahara, while the Polisario Front insists that Western Sahara’s Sahrawi people – a population the independence movement estimates at 350,000 to 500,000 – have the right to a referendum. Last year, the UN Security Council called for stepping up efforts to reach a solution to the dispute. A UN envoy brought representatives of Morocco, the Polisario Front, Algeria and neighboring Mauritania together last December for the first time in six years, followed by a second meeting in March. But the issue of how to provide for self-determination remains a key sticking point. The envoy, former German President Horst Kohler, resigned in May for health reasons. At the General Assembly, Moroccan Prime Minister Saad-Eddine El Othmani said his country’s autonomy proposal “is the solution,” while Algerian Foreign Minister Sabri Boukadoum reiterated hopes for Western Sahara residents “to be able to exercise their legitimate right to self-determination.
