UN Security Council sanctions against Libya were suspended on April 5 after secretary-general Kofi Annan officially confirmed the two Libyans accused of the 1988 Pan Am jet bombing over Lockerbie, Scotland, had arrived in the Netherlands. The sanctions, imposed in 1992 and tightened in 1993, included an air and arms embargo as well as a ban on some oil equipment. In addition, Libya's financial assets abroad were frozen but this excluded monies derived from oils sales after December 1, 1993. Sri Lanka has been the main supplier of tea to Libya, accounting for around 75 to 80 per cent of imports made by thatcountry.
