The country has developed into a centre of Islamic banking, and is the country with the highest numbers of female workers in that industry. Knowledge-based services are also expanding. To create a self-reliant defensive ability and support national development, Malaysia privatised some of its military facilities in the 1970s. The privatisation has created defence industry, which in 1999 was brought under the Malaysia Defence Industry Council. The government continues to promote this sector and its competitiveness, actively marketing the defence industry. The country is one of the world's largest exporters of semiconductor devices, electrical devices, and IT and communication products. Malaysia began developing its own space programme in 2002, and in 2006, Russia agreed to transport one Malaysian to the International Space Station as part of a multibillion-dollar purchase of 18 Russian Sukhoi Su-30MKM fighter jets by the Royal Malaysian Air Force. The government has invested in building satellites through the RazakSAT programme.
