Answer: Pakistan and Afghanistan
Notes: Trade between Pakistan and Afghanistan recently resumed as the Torkham border, a key northwestern crossing, reopened after a 10-day closure. The crossing, connecting Pakistan's Khyber Pakhtunkhwa Province to Afghanistan's Nangarhar through the historic Khyber Pass, is vital for both countries' economies. However, it has been a longstanding flashpoint due to its strategic significance and border porosity, leading to closures during clashes and, notably in 2021, being briefly seized by the Taliban during their offensive in Afghanistan.
