The Spratly Islands are 100 tiny formerly uninhabited islets and reefs making up 5 km of actual land spread over 410,000 sq km of sea. They are believed to have oil and gas reserves in addition to good fish stocks.

The problem is that both China and Taiwan lay claim to all of them and Malaysia, Brunei, Vietnam and the Philippines to part of them.

South East Asian states have just reached a draft agreement aimed at avoiding conflicts over the disputed Spratly Islands. All 10 member-states of the Association of South East Asian Nations (Asean) approved a code of conduct for the islands in the South China Sea, which will in turn be presented to China, which is not a member.

Friction over the islands, in the South China Sea, most recently erupted in August when Vietnamese troops based on one islet fired warning shots at Philippine military planes.
