Defence Minister Gerry Brownlee got a stern rebuke from China when he made the mildest of observations about Beijing's expansionist maritime policy.
At a security forum in China, Brownlee made a perfectly legitimate remark when he reminded his audience that New Zealand, as a small trading nation, was dependent on the mechanisms of international law and especially the United Nations Convention on the Law of the Sea.
The senior minister told last week's gathering: "We oppose actions that undermine peace and erode trust and would like to see all parties actively take steps to reduce those tensions."
Brownlee was referring to China's construction of artificial islands - including a military-grade air strip - in the South China Sea, activity which has rattled nerves around the region. The reclamation runs counter to the security and territorial claims of other countries in the region, and has been subject to a ruling by an international court in favour of the Philippines.
The minister made New Zealand's position clear with his comment that "we support the arbitral process and believe that countries have the right to seek that international resolution."
