The following is a guest post by Tariq Ahmad, a foreign law specialist in the Global Legal Research Directorate of the Law Library of Congress, to which I contributed. Tariq has previously authored posts on Islamic Law in Pakistan – Global Legal Collection Highlights, the Law Library’s 2013 Panel Discussion on Islamic LawSedition Law in India, and FALQ posts on Proposals to Reform Pakistan’s Blasphemy Laws and Article 370 and the Removal of Jammu and Kashmir’s Special Status.

In the last few months, there have been a number of skirmishes and stand-offs between Chinese and Indian military forces along disputed and settled parts of the Sino-Indian border. The most significant escalation took place in mid-June in high-altitude ridges of the Galwan Valley in the Himalayan region along the 2,100 mile long disputed Line of Actual Control (LAC). The LAC is a loose line of demarcation of the disputed area that is divided into three sectors, and its western sector separates the Indian-controlled territory of eastern Ladakh from the Chinese-administered territory of Aksai Chin (which is also claimed by India).

Failure to resolve the border dispute resulted in the 1962 Sino-Indian War and there has been no final agreement between the countries on the exact location of the LAC. According to Alyssa Ayres, a South Asia expert at the Council on Foreign Relations, “China and India have differing ideas of where it should be located, leading to regular border “transgressions.” Often these don’t escalate tensions; a serious border standoff like the current one is less frequent, though this is the fourth since 2013.”

The June 15th border clash was reported to have happened during an apparent “de-escalation process” weeks after “high-level military commanders from both nations” agreed on June 6th to “peacefully resolve the situation in the border areas in accordance with various bilateral agreements.” The clash on the ridge reportedly involved hand-to-hand combat with iron bars, rocks, and fists, leading to the deaths of 20 Indian soldiers and an undisclosed number of Chinese soldiers. While neither side carried guns, most of the soldiers killed in the fighting lost their footing or were knocked from the narrow Himalayan ridge, plunging to their deaths. These are the first deaths along the LAC since 1975.

Though the exact details of the June 15th clash and the reasons for why things have “escalated now to their worst in decades” are a bit unclear, some experts have pointed to a number of factors, including both sides claiming violations of pre-existing agreements, military buildup and infrastructure/road developments in proximity of the LAC, and the revocation of the autonomous status of Jammu & Kashmir by the Indian government which resulted in the establishment of the Union Territory of Ladakh, as contributing to the current impasse. Senior Indian and Chinese military commanders are currently in their fourth round of talks to “negotiate the next stage of disengagement between the two armies along the Line of Actual Control (LAC),” in an attempt to “reduce tensions along the disputed border.” Diplomatic level talks and negotiations have also been conducted by the Special Representatives (SRs) on the Boundary Question, which was established in 2003, and the Working Mechanism for Consultation & Coordination on India-China Border Affairs (WMCC)created in 2012.

Since the 1962 war, the two countries have entered into various bilateral agreements as Confidence Building Measures (CBMs) to prevent the situation from escalating, including the much-reported 1996 agreement and the “prevalent practice” of not using guns near the LAC that flows from this and other agreements. Below we have outlined the various bilateral agreements and the authoritative government and international sources where they can be accessed:

  • 1993 Agreement on the Maintenance of Peace and Tranquility along the Line of Actual Control in the Sino-Indian Border

According to a summary on the UN Peacemaker website, this agreement provides the “framework for border security between the parties until final determination is made regarding border demarcation.” The parties agree to keep “military forces in the areas along the line of actual control to a minimum level” and “reduce troop levels” compatible with friendly and good relations between them. (Art. 2.) They also agree to carry out confidence-building measures along the LAC control, including by providing prior notification of “military exercises of specified levels near the line of actual control permitted under this Agreement.” (Art. 2.)

It specifies the major categories of armaments to be reduced or limited: “combat tanks, infantry combat vehicles, guns (including howitzers) with 75 mm or bigger calibre, mortars with 120 mm or bigger calibre, surface-to-surface missiles, surface-to-air missiles and any other weapon system mutually agreed upon.” (Art. 3.)
