President Tran Dai Quang and Prime Minister Peter O'Neill met at APEC in Lima, Peru, and discussed co-operation in agricultural skills and development as well as the prospect of establishing a PNG Embassy in Hanoi.
"Papua New Guinea and Vietnam have a strong and deepening relationship and the time has come to establish a permanent foreign mission in Hanoi," O'Neill said.
"This office will be an important conduit for us to not only expand trade and investment, but to draw on Vietnam's experience in areas such as coffee and rice production.
"Vietnam has recently increased coffee production, and while we are targeting similar markets, there is agricultural technical information that we can share that will benefit producers in both countries," O'Neill said.
O'Neill noted that PNG was a rice importer and given the fertility and climate, should be able to produce enough for its own requirements.
"As we increase our technical capacity, through partners such as Vietnam and though APEC projects, and we encourage greater investment in rice production we will see our rice production steadily increase."
