The Chinese Embassy in Wellington has lodged a formal diplomatic complaint — known in diplomatic language as "solemn representations" — with the Ministry of Foreign Affairs and Trade (MFAT) over comments made by Foreign Minister Winston Peters during a parliamentary debate on Thursday, 30 July 2026.

During the exchange, Peters told Green MP Lawrence Xu-Nan, who has lived in New Zealand since 1994, to "go back to your own country." Peters also told Xu-Nan: "This is called a democracy, unlike what you're used to." The remarks were directed at a New Zealand parliamentarian of Chinese descent during a sitting day in the House.

The Embassy's complaint referenced what it called "negative China-related remarks made by a certain politician in the New Zealand Parliament." It urged New Zealand to "value the equal and mutually beneficial relationship between China and New Zealand and to do more things conducive to bilateral relations rather than the other way around." The Embassy also called on New Zealand to create "an open, inclusive and non-discriminatory environment" for the Chinese community to "study, live and work in New Zealand." (RNZ)

China's Ambassador to New Zealand, Wang Xiaolong, addressed the matter on social media. Wang said New Zealand's domestic politics were not China's concern, but added: "sometimes, a statement says more about the person that makes it than anything or anybody else." (RNZ)

A spokesperson for Peters confirmed he was briefed on an MFAT official's conversation with the Chinese Embassy on the afternoon of the same day the complaint was lodged. Peters has served as Foreign Minister across multiple terms and has made seven official visits to China, most recently in late 2025. (RNZ)

Xu-Nan described Peters' conduct as "repeated behaviour and racism" and called on the Prime Minister to hold Peters to account. The Green MP has been a member of Parliament and was first elected as a list MP under New Zealand's MMP system, where parties fill seats based on their share of the party vote. He has resided in New Zealand for over three decades. (RNZ)

Foreign embassies in Wellington routinely monitor parliamentary proceedings, but formal complaints to MFAT over remarks made during House debate are not commonplace. The Embassy's decision to frame Peters' words as a matter affecting the Chinese community in New Zealand, rather than solely as a diplomatic dispute between two governments, widens the issue beyond foreign policy into domestic social cohesion.

Ambassador Wang's social media post struck a deliberately measured tone. By attributing the remarks to Peters' character rather than to the government or Parliament as an institution, he distanced Beijing from direct interference in New Zealand politics while leaving the criticism intact. That phrasing keeps the diplomatic channel functional while still registering displeasure.

Peters' own history with China policy gives the episode additional weight. In May 2024, he publicly described the New Zealand–China relationship as "complex" and called out what he characterised as hardening rhetoric. In February 2025, ahead of a three-day visit to Beijing, Peters flagged his intention to question Chinese naval activity directly with his counterparts. (Reuters; Reuters) These positions place Peters as a minister willing to articulate differences with Beijing in public, even as he has maintained an active programme of engagement through repeated visits.

The broader context here is that three separate pressures have converged on the coalition government at once: a personal attack in the House directed at an MP on the basis of ethnicity, an embassy invoking the welfare of the Chinese community in its complaint, and a foreign minister whose portfolio requires him to manage the very bilateral relationship now under strain. Peters is both the source of the remarks and the minister responsible for the relationship with the country that has complained — that is the central tension. How the government navigates it, and whether the Speaker or the Parliamentary Privileges Committee takes any interest in the original exchange, will be the markers to watch.

MFAT's handling of the complaint, and any further response from Peters or his office, will determine whether the matter remains a single news cycle or develops into a sustained diplomatic and political issue.
