Parties involved in maritime disputes should use peaceful means to settle their differences in line with international law, said a candidate for UN secretary-general.

Danilo Turk, a former president of Slovenia, made the remark on Tuesday when asked by China Daily to comment on China's call for direct dialogue and negotiation with countries in dealing with maritime disputes.

"Every dispute settlement process includes the element of negotiation. It is fundamental that parties to a dispute retain communication throughout the dispute settlement process," Turk said.
