Malaysia Prime Minister Najib Razak urged for a rapid conclusion to the long-stalled drafting of a code of conduct for the South China Sea, The Wall Street Journal reported, citing a speech by the PM. The call comes after a tense weekend at the Asia Security Summit in Singapore, where China traded barbs with the US and smaller Asian neighbours over Beijing’s claims to disputed waters. Diplomatic progress has taken on new urgency as China increasingly uses its strengthening military to assert its claims to nearly the entire sea.
