Services dominate the Pakistani economy. In 1998, they contributed 48.2 percent to GDP, while agriculture and industry each accounted for about a quarter of gross domestic production (25.2 percent and 26.6 percent, respectively). After the crisis following the nuclear standoff with India and the subsequent international sanctions against Pakistan in May 1998, value-added large-scale manufacturing was projected to grow by only 2.4 percent in 1998-99, sharply down from 6.2 percent in 1997-98. Growth of the agricultural sector, too, was expected to be only about half the level of the previous year. The manufacturing sector has seen dramatic fluctuations, averaging 9 percent per year during the first 2 decades of independence, but dropping to less than 3 percent in the 1970s, when large-scale nationalization significantly reduced investment levels. The rate recovered in the 1980s, averaging 7.6 percent, but fell back to 3.9 percent in the 5 years prior to 1999-2000.
