Thousands marched in Cairo on April 15 to protest President Abdel Fattah al-Sisi's decision to turn two disputed islands over to Saudi Arabia. Crowds chanted slogans such as "Sisi – Mubarak," "We don't want you, leave," and "The people want the downfall of the regime"—the iconic slogan of the Arab Revolution. Security forces responded with tear-gas; at least 25 were detained and are being held on charges of violating Egypt's controversial anti-protest law. More protests are planned for this weekend, and on April 22 security forces carried out pre-emptive arrests of noted activists in an apparent effort to head them off. Cafes in downtown Cairo were raided and activists seized from their homes, prisoners' rights group Freedom for the Brave said in a statement on Facebook. Pre-emptive arrests were also reported in Alexandria and in Gharbeyyia governorate.

The UN Commission on the Limits of the Continental Shelf (CLCS) ruled on March 28 that Argentina's maritime territory includes the area surrounding the Falkland Islands. Argentina had previously submitted to the commission a report fixing the territory at 350 [nautical] miles from its coast instead of 200. The commission made clear that it was not in a position to consider and qualify parts of the submission that are subject to dispute. The commission's findings expand the maritime territory of Argentina by 35%. Susana Malcorra, Argentina's foreign minister, maintained that the findings reaffirm the country's sovereignty rights over the resources of its continental shelf. The findings have been dismissed by the UK as recommendations that are not legally binding.

Bolivian President Evo Morales announced March 26 that his government will bring suit against Chile before the International Court of Justice seeking compensation for using the waters of the disputed Río Silala. Two days later, he made a visit to the river in Potosí department, where he declared, "Silala is not an international river." Chile's President Michelle Bachelet promptly responded that Bolivia has recognized the Silala as an international river for more than 100 years and said she would counter-sue before the World Court if Bolivia in fact brought a case. Originating in the high desert plateau of Bolivia's remote southeast, the Silala flows into Chile through a canal built for mining operations over a century ago. In 2009 Chile and Bolivia announced an accord to resolve the conflict, which would cut Chile's use of the Silala's water by 50%. But the pact was never formalized, and local communities in impoversihed Potosí demanded retroactive payment for Chile's past use of the waters.

Taiwan's President Ma Ying-jeou made a provocative visit Jan. 28 to Taiping Island in the South China Sea—the largest natural island in the dipsuted Spratly chain. Taiwan has controlled Taiping Island (also known as Itu Aba) since 1946, but it is also claimed by the Philippines, Vietnam—and, significantly, China. The island is inhabited by only 200—all Taiwanese military personnel. In his visit, Ma boasted infrastructure developments, including a new hospital and a lighthouse—but his comments made clear this was aimed at establishing what the diplomats call "facts on the ground." The island already hosts fortifications, military barracks, a hospital, radar and satellite facilities. "All this evidence fully demonstrates that Taiping Island is able to sustain human habitation and an economic life of its own," Ma said in a press release. "Taiping Island is categorically not a rock, but an island."  He also officially unveiled a monument during his visit, with an inscription reaing: "Peace in the South Seas, Eternally Secure the National Borders."

A Kashmir-based militant coalition, the United Jihad Council, claimed responsibility for an attack on the Indian air force base at Pathankot, which has left five militants and seven soldiers dead in three days of fighting. The attack on Pathankot—in northern Punjab state, near the borders with both Jammu & Kashmir state and Pakistan—is seen as an attempt to derail recent peace moves by India and Pakistan. The attack came about a week after a surprise visit by India's Prime Minister Narendra Modi to his Pakistani counterpart Nawaz Sharif—the first Islamabad visit by an Indian premier in 12 years.

A change of government in Guatemala and Belize is reviving long-simmering fears of war between the Central American neighbors. Media in Belize are reporting that a leaked document written by a senior officer in the Belize Defense Force apparently claims an ongoing campaign of aggression and confrontation from the Guatemalan military along the Sarstoon River, which forms the border between the two nations in the south. The leaked memo, dated Oct. 22, notes incidents as far back as 2003, with tension reaching dangerous point in 2006. The tension eased when the two nations' armed forces agreed on protocols for their border forces along the Sarstoon. But the memo says late 2009 saw another incident, in which a Guatemalan army vessel anchored on the Belizean side near the mouth of the Sarstoon, and raised a Guatemalan flag from a tree-top. BDF troops apparently removed the flag, but that the Guatemalan soldiers defiantly promised to replace it.

The Permanent Court of Arbitration (PCA) in The Hague ruled (PDF) Oct. 29 that it has jurisdiction to hear a dispute between the Philippines and China over parts of the South China Sea. At issue are a number of islands and shoals, which the Philippines says China has annexed illegally under the UN Convention on the Law of the Sea. China has long held that the PCA lacks jurisdiction to hear the case, saying that it would be open to bilateral negotiations with the Philippines over the issue. China has boycotted the proceedings, rejecting the court's authority in the case. Beijing claims sovereignty over almost the entire South China Sea, maintaining that its rights are based on history rather than legal precedent.

On Oct. 12, proclaimed as the Day of Indigenous Resistance, the Kichwa organization ECUARUNARI announced that its president Carlos Pérez Guartambel succeeded in entering Ecuador with a passport issued by the Kichwa Nation. Border authorities initially held Pérez, saying the document was "illegal," but ultimately let him pass. ECUARUNARI said the passage "marks an historic precedent at the juridical level for all Abya Yala," using the pan-indigenous name for the Americas (adopted from the Kuna people of Panama). The statement also hailed the passage as another "step towards a pluri-national" state in Ecuador. (Pueblos en Camino) The report does not state what country Pérez entered from, but it was presumably Peru. The Peru-Ecuador border divides the territory of the Kichwa and several other indigenous peoples.
