BNP staged a walkout from parliament in August 1997. The BNP returned to Parliament under another agreement in March 1998. In June 1999, the BNP and other opposition parties again began to abstain from attending Parliament. Opposition parties have staged an increasing number of nationwide general strikes, rising from 6 days of general strikes in 1997 to 27 days in 1999. A four-party opposition alliance formed at the beginning of 1999 announced that it would boycott parliamentary by-elections and local government elections unless the government took steps demanded by the opposition to ensure electoral fairness. The government did not take these steps, and the opposition has subsequently boycotted all elections, including municipal council elections in February 1999, several parliamentary by-elections, and the Chittagong city corporation elections in January 2000. The opposition demands that the Awami League government step down immediately to make way for a caretaker government to preside over parliamentary and local government. In March 2000, US President Bill Clinton became the first US president to visit Bangladesh. Hasina later stated that during the visit Clinton wanted to import gas from the Country, but she had to decline due to fear of scarcity of gas and for the welfare of the people as they were heavily dependent on gas.
