Following its investment, Cnergyico plans to boost production of Euro-V compliant high-speed gasoline and diesel while reducing furnace oil production in response to declining and unpredictable demand. Pakistan has faced several economic challenges in recent times, including political instability, soaring inflation, a weakening currency and dwindling foreign exchange reserves. These factors have eroded investor confidence, making local and foreign investors reluctant to commit capital to major projects.
