By Andrew Torchia DUBAI, March 30 (Reuters) - Saudi Arabia will use multi-billion dollar infrastructure projects to attract foreign investment in sectors such as transport, healthcare and industrial equipment, a senior eco**mic official said on Monday. Prince Saud K. Al Faisal, executive director for investment policy at the Saudi Arabian General investment Authority, said that under a new programme, the government would propose investments linked to such state spending plans. Prince Saud said the programme represented a shift in focus for Saudi Arabia, towards using foreign investment to obtain tech**logy and high-quality jobs and away from emphasising the monetary size of investments. Investors that establish export bases in Saudi Arabia will be given priority, he said.
