Tensions have been flaring between Chile and its neighboring countries, Bolivia and Peru.

TeleSUR reported that Chile is carrying out land, air, and sea military exercises along its northern border region. Bolivia and Peru are currently making noteworthy progress in attempting to reclaim their territories lost to Chile in the War of the Pacific, which took place from 1879 to 1883.

Bolivia and Peru have called Chile's military maneuvers as an act of intimidation, teleSUR wrote. The "Huracan 2015" is one of the biggest military exercises conducted by Chile in the region this year, according to a report from the World Socialist Web Site, or WSWS, on Tuesday. For "Huracan 2015," more than 5,500 troops were deployed, with tanks, frigates, submarines, and combat and transport aircraft mobilized as well on Chile's northern border with Bolivia and Peru.

The three nations have been locked in a territorial spat over Chile's coastline, which Chile took from Bolivia and Peru during the War of the Pacific, the news outlet added. The loss of territory made Bolivia a landlocked country.

In November, Bolivian President Evo Morales called Chile's maneuvers an act of intimidation.

"Maybe some conservative groups in Chile still think that these kinds of exercises of the Armed Forces will intimidate Peru, and Bolivia," said Morales, as quoted by teleSUR. "They are wrong. With this kind of action, only the dignity of the Chilean people is damaged."

Bolivia and Chile's diplomatic relations have been limited since 1978, the Guardian wrote. After several unproductive negotiations with Santiago, Chile's capital, over the subject, the Bolivian administrative capital, La Paz, filed a complaint to the Hague-based International Court of Justice, or ICJ, in April 2013.

In February, the ICJ granted Peru authority over 50,000 square kilometers of open ocean that Chile had formerly claimed as part of its national waters, the news outlet further reported. In September, the ICJ announced that it would consider Bolivia's claim demanding for access to the sea.

The WSWS stated that despite Chile's military exercises conducted annually since 2000, this year's was regarded as "by far the most menacing," teleSUR added. However, the country insisted that the boosted military maneuvers were intended to fight crime-related problems along the border.

Chile said its territorial sovereignty was still in line by treaties signed in 1904 and 1948, which prevents an international court from meddling in the matter. However, the treaties do not indicate "Chile's alleged obligation to negotiate Bolivia's access" to the sea and as a result, "Chile's objection to jurisdiction ... must accordingly be dismissed," ICJ Judge Ronny Abraham said, the Guardian reported.
