Dr. Al-Yahya commented on the key role of workers’ remittances in the economy of LDCs, whose nationals seek employment abroad and send money home, pointing out that Saudi Arabia is the source of around $17 billion annually in this respect. The recipients of these remittances, he suggested, should be encouraged to invest in small business development instead of buying consumer products. He went on to say that part of the problem for sustainable development is that some countries are in dire circumstances through no fault of their own, vulnerable to external shocks because of their geographical location and the fluctuations of international markets, and referred specifically to the shadow cast over the entire Middle East region by the failure to resolve the Israeli-Arab dispute. Another part of the problem is the need to establish a sound macroeconomic policy by eliminating unnecessary tax incentives and improving tax administration, since inefficient infrastructure impedes the flow of commerce, especially for exports.
