China recently expressed its displeasure to New Zealand over the Government's new Strategic Defence Policy Statement.
The policy statement was unusually explicit for New Zealand in its criticism of China's military build-up in the South China Sea and also referred to China's activities in the Antarctic.
It also emphasised the need for New Zealand to stand ready to help its partners.
Peters, in a major foreign policy speech in June, also talked about the militarisation of the South China Seas without mentioning China, which was in keeping with the last Government's practice.
"We see some troubling developments. In the South China Sea, claimants in the various territorial disputes have acted in ways that challenge international law and norms."
Peters also included some guarded criticism of the United States, in an apparent reference to its need to uphold a rules-based order in international trade.
"Our emphasis on international law, inclusivity, economic integration, trade, and respect for sovereignty makes us a constructive regional partner for most states," Peters said.
