The document discusses the causes of poor and good relations between Pakistan and Bangladesh. Poor relations stemmed from the 1971 war of independence, civil war, Pakistan initially refusing to recognize Bangladesh, and disagreements over dividing assets. Good relations emerged after the 1976 assassination of Mujeeb, with improving agreements around tourism, culture, and trade such that bilateral trade reached $40 million annually by 1986. Both countries also joined organizations like SAARC and assisted each other during natural disasters.
