The China Pakistan Economic Corridor (CPEC) is a $46 billion investment by China in Pakistan that aims to improve connectivity between the two countries. CPEC will upgrade infrastructure like roads, railways, and pipelines to provide China easier access to the Middle East and African markets. It will also establish an economic corridor to boost trade, energy, and industrial cooperation. CPEC is expected to benefit both countries by shortening trade routes for China and developing infrastructure and industries in Pakistan.
