China has recently rejected India’s territorial claim over the Shaksgam Valley, asserting that the region forms part of Chinese territory.India maintains that the area is part of the larger Jammu & Kashmir region, and therefore an integral part of India. The renewed statements have brought the strategically sensitive region back into focus.

About Shaksgam Valley

The Shaksgam Valley, also known as the Trans-Karakoram Tract, is a disputed territory located in the northernmost part of the Kashmir region.

• It is part of the Hunza-Gilgit region of Pakistan-Occupied Kashmir (POK).

• It is claimed by India but controlled by Pakistan, and currently administered by China following a boundary agreement.

Geographical Location

The valley occupies a strategically important position:

• To the north, it borders Xinjiang of the People’s Republic of China.

• To the south and west, it is bordered by the Northern Areas of POK.

• To the east, it lies close to the Siachen Glacier, one of the world’s highest and most militarised battlefields.

1963 Sino-Pakistan Boundary Agreement

In 1963, Pakistan and China signed a boundary agreement under which Pakistan ceded the Shaksgam Valley to China to settle their border differences.

However, Article 6 of the agreement clearly stated that:

After the settlement of the Kashmir dispute between Pakistan and India, the sovereign authority concerned would reopen negotiations with China to sign a formal boundary treaty.

This clause indicates that the agreement was considered provisional, pending the final resolution of the Kashmir dispute.

India has consistently rejected the agreement, arguing that Pakistan had no legal authority to cede territory that legally belongs to India.

Strategic Importance

The 1963 agreement laid the foundation for deeper Sino-Pak cooperation, including the construction of the Karakoram Highway in the 1970s by Chinese and Pakistani engineers.

The region is strategically significant because:

• It lies near the China-Pakistan Economic Corridor (CPEC) routes.

• It connects Xinjiang with Pakistan’s northern territories.

• It is close to the Siachen sector, making it sensitive from a military and geopolitical perspective.

Why It Matters for India

• India considers the entire region of Pakistan-Occupied Kashmir, including Shaksgam Valley, as its sovereign territory.

• The 1963 agreement is viewed by India as illegal and invalid.

• The issue has implications for India–China relations, India–Pakistan relations, and broader regional security dynamics in the Karakoram region.
