Argentina–Chile border

Road in the border area between Santiago and Mendoza.

The Argentina–Chile border is the longest international border of South America and the third longest in the world after the Canada–United States border and the Kazakhstan–Russia border. With a length of 5,308 kilometres (3,298 mi),[1] it separates Argentina from Chile along the Andes and on the islands of Tierra del Fuego. However, there are some border disputes, particularly around the Southern Patagonian Ice Field. It is the largest border of the two countries, beating the Argentina–Paraguay and Chile–Bolivia, Argentina's and Chile's second largest borders, respectively.

Description

[edit]
This map shows the current border in the Southern Patagonian Ice Field, the B Section is pending to be defined.

The northern end of the border is a tripoint it forms with those at the Argentina–Bolivia border and the Bolivia-Chile border in the arid Puna de Atacama plateau. The border extends south until reaching the sea at the same place the Strait of Magellan meets the Atlantic Ocean. Further south the border on the Isla Grande de Tierra del Fuego follows a meridian separating the island into two. This boundary reaches the sea at Beagle Channel a few kilometers southwest of Ushuaia.

In November 1984 the southern border area was finally established after long negotiations and mediation of John Paul II by the Treaty of Peace and Friendship of 1984 between Chile and Argentina, a perpetual treaty, signed at the Vatican by representatives of both countries.

On 16 December 1998, an agreement between Argentina and Chile was signed to redefine the border line from Mount Fitz Roy and Mount Daudet and finish with the historical dispute. However both countries didn't agree in the section between Mount Fitz Roy and Mount Murallón, and the border is still pending to be defined. Only Chile shows this on the cartography, while Argentina shows its pre-1998 claim, not following the new border between Murallón and Daudet from the agreement, nor indicating the pending section.

Overlapping Argentine and Chilean Antarctic claims on Antarctica (1946–present).

The territorial claims of Argentina and Chile over Antarctica partially overlap with each other. Chile claims for itself the Chilean Antarctic Territory, which is included in the Region of Magallanes and Chilean Antarctica, while Argentina claims Argentine Antarctica, whose territory is part of the Province of Tierra del Fuego, Antarctica and South Atlantic Islands.

Both countries recognize each other's territories that do not overlap with their own as stipulated in the protocols of 1947, 1948, 1964, 1971 and 1978.[2]

Dispute over the extended continental shelf

[edit]
Map of the dispute.
This section is an excerpt from Dispute over the extended continental shelf in the Southern Zone Sea between Argentina and Chile § History.[edit]

In 2009, Argentina submitted a presentation to the United Nations Commission on the Limits of the Continental Shelf, which was accepted in 2016 by the UNCLOS.[3] The map in the submission included the disputed territories with the United Kingdom, such as the Falkland Islands, South Georgia, and South Sandwich Islands, a crescent-shaped area south of Argentina's territorial sea as defined in the 1984 treaty with Chile.[4] This area was also claimed by Chile as part of its Presential Sea,[5] and the sea surrounding the Antarctic Peninsula, which is claimed by all three aforementioned countries.[6]

In 2020, the Argentine Chamber of Deputies unanimously approved the outer limit of the Argentine Continental Shelf in Law 27,557.[7]

In 2021, Chilean President Sebastián Piñera signed Supreme Decree No. 95, which outlined the continental shelf east of the 67º 16' 0 meridian as part of Chile's continental shelf (not the extended one) area projected from the Diego Ramírez Islands, also claiming the crescent area that Argentina considers part of its extension achieved under the extended continental shelf principle.[8][9][10] This was reflected in the SHOA Chart No. 8[11] and prompted a response from the Argentine Foreign Ministry against Chile's measure.[12][13][14][15][16][17]

In 2023, Chile, through SHOA, made available an illustrative graphic showing all the maritime areas claimed by the country, which was once again rejected by Argentina.[18][19][20][21]

In addition, Chile will present its claim regarding the extended continental shelf west of the territory it claims in Antarctica as the Chilean Antarctica to the United Nations' CONVEMAR.[22]

In July 2023, the International Court of Justice ruled on the priority of a Continental Shelf over a Extended Continental Shelf in the case of the territorial and maritime dispute between Colombia and Nicaragua.[23]
