Papua New Guinea Prime Minister Peter O’Neill will sign an agreement to join China’s Belt and Road Initiative Infrastructure Program in a week-long official visit.

Alongside East Timor, PNG will be the second Pacific nation to sign to the agreement in a move that worries Australian officials.

Chinese loans make-up a quarter of PNG’s national debt, but PM O’Neill says the agreement is important for PNG to integrate into the global economy and that it’s unwise to simply sit back and let these opportunities pass by.
