They will also ask countries which fish in Tongan waters to pay increased fees.
Ministry of Labour and Commerce CEO Edgar Cocker said higher fees would help Tonga’s economy.
“There are rich countries which have refused to do this, but I will lobby them to try to change their minds,” Cocker said.
Tonga’s balance of trade needed change for the good of the economy and the country needed to boost exports in 2018.
Minister of Labour and Commerce Dr Pohiva Tu’ionetoa and Cocker will attend the WTO Trade Ministerial meeting in Argentina.
