Pak-US- Relations may be sour these days, but a new trade development could sweeten up things. The first shipment of Pakistani mangoes arrived at O'Hare International Airport. Pakistani Ambassador to US Husain Haqqani credited "two years of strategic dialogue" for the shipment. He said the mango trade will improve relations between the two countries. The fragrant chaunsa mangoes won’t be in stores for a few weeks. Only acrowd at the Palmer House Hilton got an early taste. Pakistani-American guests strolled the hotel’s ballroom sampling chilled mango chunks, mango ice cream, mango tarts and other delicacies. Farahnaz Ispahani, the wife of Haqqani and the Pakistan presidential spokeswoman, said. "The soil in Pakistan produces the sweetest mangoes in the world and once Americans taste Pakistani mangoes in all their depth and flavors they’ll never turn back. They ‘ll forget Alphonsos and any other mangoes."
