Poor quality and insufficient electricity supplies have hampered the investment climate for decades but recent investments have reduced the reliance on imports and altered the energy mix towards cheaper options. As elsewhere in Southeast Asia, special economic zones are slowly starting to diversify sources of foreign investment, both by sector and by country'. One manifestation of this is the long delays in drafting and implementing laws. The amendment to the Investment Law and the enactment of the Law of Special Economic Zones have been debated for several years and are still pending, as is a Competition Law which was first mooted as part of WTO accession.
