This was the statement from the PNG Opposition Leader, Don Pomb Polye, after his historic visit to Batas on Saturday.
The Opposition Leader said both governments needed to encourage businesses to build permanent buildings on each side of the border to sell their items.
"Trade worth more than K3 million takes place at the border without any proper control by authorities. It adds to the tally of total capital outflow," he said.
After the trip, Polye said he learnt that PNG faced trade deficit there.
