How important is the China Pakistan secret project Karakoram Highway

The China Pakistan secret project, Karakoram Highway, holds significant importance. It symbolizes the deep friendship between China and Pakistan, serving as a vital link between the two countries. Built in the 1960s and 1970s, it spans 1,224 kilometers, starting from Kashgar, Xinjiang in China and ending in Thakot, Pakistan. Considered the highest and most beautiful highway in the world, it is also known as the "Eighth Wonder of the World" and one of the "Top Ten Precipitous Highways." The highway serves strategic purposes, facilitating land transportation between China, South Asia, the Middle East, and the Near East. It was constructed through the joint efforts of Pakistan's Army Engineer Corps and China's Xinjiang Production and Construction Corps. The challenging terrain of the Karakoram Mountains and other mountain ranges posed difficulties, including heavy snowfall, natural disasters, and high altitudes. The workers overcame these challenges and hardships, including altitude sickness, to construct the road. The construction of the Karakoram Highway opened up trade routes for China towards the west and strengthened the western border defense of both countries. Despite ongoing challenges such as landslides and harsh weather conditions, the highway remains a testament to the strong bond between China and Pakistan.
