|Professor Ross Garnaut and Sir Mekere Morauta|
According to the newspaper, BHP said in a Department of Foreign Affairs and Trade document, that PNG's treatment of Prof Garnaut sent “a very bad message’’ to companies looking to do business in the country.
The miner also took aim at PNG Prime Minister Peter O’Neill, accusing the leader of improper dealings in the granting of of exploration licences.
In November, the PNG foreign affairs department was instructed to prevent Professor Garnaut entering the country after the prime minister said the Australian was no longer welcome and accused him of insulting to the nation's leaders.
During a grievance debate in parliament a few days before the November decision, Mr O'Neill referred to a report in The Australian newspaper quoting Prof Garnaut as saying that with such an accumulation of wealth in PNG, it was "tempting for political figures to think of better ways of using it right now rather than putting it into long-term development".
