Which was already in Pakistani control already, i.e Hunza region.
China only backed off it's claim on Hunza, which was unjust.
While Paks handed Pamiri regions and shaksgam valley to china.

That's like Pak asking for Kashgar.
Essentially Pak lost people and territory and gained nothing but a recognition.
It was/is Chinese territory until the British illegally claimed it.
"The
Sino-Pakistan Agreement[a] is a 1963 document between the governments of
Pakistan and
China establishing the border between those countries in the disputed
Kashmir region.
[3]
It resulted in both countries ceding over 1,942 square kilometres (750 sq mi)[clarification needed] to the other. Pakistan recognized Chinese
sovereignty over land in
Northern Areas of Kashmir and
Ladakh.
[4][5] However, Indian writers have insisted that in this transaction, Pakistan surrendered approximately 5,300 km2 (2,050 sq mi) of territory to China.
[6][7] India claims the agreement is invalid, and claims sovereignty over part of the land. In addition to increasing tensions with India, the agreement shifted the balance of the
Cold War by bringing Pakistan and China closer together while loosening ties between Pakistan and the
United States."
"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 never under the control of Pakistan since 1947, in the 1963
Sino-Pakistan Agreement, Pakistan recognized Chinese sovereignty over the Shaksgam tract, while China recognized Pakistani sovereignty over the
Gilgit Agency, and a border based on actual ground positions was recognized as the international border by China and Pakistan.
[4][5] It, and the entire Kashmir region, is claimed by India.
