Saudi Arabia and South Korea have signed key accords on the development of nuclear energy including a plan to study the feasibility of building nuclear reactors worth SR7.5 billion ($2 billion) across the kingdom.

The duo will co-operate on the development of nuclear energy, Saudi state news agency SPA said, building on a deal signed in 2011.

South Korean President Park Geun-hye met Saudi Arabia's King Salman on Tuesday in Riyadh during an official visit, SPA said.

The MoU calls for South Korean firms to help build at least two small-to-medium sized nuclear reactors in Saudi Arabia, the South Korean presidential office said in a statement.
