The Vanuatu Daily Post reports this appeal from Charlot Salwai came on his return from signing the regional PACER Plus trade agreement during the Forum summit in Samoa.
Mr Salwai was reacting to criticism of the move from the Vanuatu Chamber of Commerce and Industry.
The Chamber said Vanuatu already had a reputation as a difficult country to do business in and with the possibility of an income tax being brought in investors could choose to move to other Pacific countries.
But Mr Salwai said Vanuatu wants to provide opportunities for business to flourish and this could be achieved through PACER Plus.
The paper also reported the prime minister warning against implementing protectionist policies.
