Economic growth in the West Bank - the larger of the two areas comprising the Palestinian territories - has slowed since 2013, in part because of a decline in donor aid and government spending. Private sector development has been weak. Despite the Palestinian Authority's (PA) successful implementation of economic and security reforms and the easing of some movement and access restrictions by the Israeli government, Israeli closure policies continue to disrupt labor and trade flows, industrial capacity, and basic commerce, constraining the productive capacity of the West Bank economy. The biggest impediments to economic improvements in the West Bank remain Palestinians' inability to access land and resources in Israeli-controlled areas, import and export restrictions, and a high-cost capital structure. The PA for the foreseeable future will continue to rely heavily on donor aid for its budgetary needs and economic activity.
