Singapore has signed an Open Skies Agreement (OSA) with the South Pacific island nation, Tonga.

The agreement allows airlines of both countries to fly between Singapore and any points in Tonga without restrictions in capacity, frequency or aircraft type.

Transport Minister Lui Tuck Yew and Tonga's Prime Minister and Minister for Foreign Affairs, Defence, and Information and Communication, Lord Tu'ivakano signed the agreement in Singapore on Monday.

Mr Lui said that the agreement reflects the warm bilateral ties between the two countries and underscores the countries' commitment to establish a "full liberal air services framework" that will allow carriers to respond quickly to market demand when opportunities arise.
