evidence: The Trans-Karakoram Tract (Chinese: 喀喇昆仑走廊; pinyin: Kālǎkūnlún zǒuláng), also known as the Shaksgam Tract (Urdu: شکسگام, romanized: Shaksgām), is an area of approximately 5,200 km2 (2,000 sq mi)[1] north of the Karakoram watershed, including the Shaksgam valley.[2][3] The tract is administered by China as part of its Taxkorgan and Yecheng counties in the Xinjiang Uyghur Autonomous Region. Although the Shaksgam tract was originally under the control of India following the accession of Jammu and Kashmir to India in 1947, Pakistan took control of the region after the First India-Pakistan War and subsequently ceded it to China in 1963 through the Sino-Pakistan Agreement, and a border based on actual ground positions was recognized as the international border by China and Pakistan.[4][5] The Shaksgam Tract, along with the entire Kashmir region, is claimed by India.[6][7] Further, New Delhi has never accepted the China-Pakistan boundary pact, asserting that Islamabad "unlawfully" attempted to cede the area to Beijing.[8] [...] The Shaksgam Valley was never part of Kashmir and the northern and eastern boundaries of Kashmir were undefined - ^ a b "Signing with the Red Chinese".
