The US ambassador to Mexico told an investor conference that China would gain from an insecure Mexico. He named no company and announced no measure.
The US ambassador to Mexico, Ronald Johnson, said on Wednesday, 28 October, that China would benefit from a chaotic and insecure Mexico. He spoke at an investor conference in Mexico City, in a session on US-Mexico relations.
He also questioned China’s sincerity in wanting to operate in Mexico, so close to the United States. China in Mexico matters to US readers because Washington treats Chinese business next door as a security question.
What Johnson Said in Mexico City
Johnson spoke at the Milken Institute Global Investors’ Symposium, held by a US economic think tank. His session was titled “US-Mexico Relations: Strategic Priorities and Shared Interests”.
China would benefit from Mexico being “a chaotic and insecure place” on the southern border of the United States, he said. He added that China would back companies that cost it money, to create dependence.
He questioned China’s “sincerity” in wanting to operate in Mexico, “so close to the United States”. The quotes are translations from Spanish-language reports of the speech.
The North American Alternative He Offered
Johnson said Mexico, the United States and Canada could turn their own resources into products and sell them worldwide as one bloc. He said the border does not have to be a barrier, because it also offers opportunities.
The US interest is partly selfish, he said, because a safe, prosperous Mexico is good for the United States. Canada’s ambassador to Mexico, Cameron Mackay, and Mexico’s finance secretary, Édgar Amador Zamora, also took part in the event.
Who Is Who in Plain English
- Ronald Johnson: US ambassador to Mexico since 2025, a former Army officer and intelligence veteran who also served as US ambassador to El Salvador.
- Claudia Sheinbaum: Mexico’s president since October 2024, from the left-wing Morena movement; she holds a daily morning press conference.
- APEC: the Asia-Pacific Economic Cooperation forum of 21 economies, which includes the United States, China and Mexico.
- USMCA, or T-MEC in Spanish: the trade pact linking Mexico, the United States and Canada.
China, Mexico and the US Border Zone
Chinese manufacturers have looked to Mexico to build goods nearer US buyers and sidestep tariffs, which has caused friction with Washington. Johnson named no company and gave no figures in the remarks as summarised.
Sheinbaum said on Wednesday, 23 September, that she will go to China in November for the APEC summit. Mexico hosts the forum in 2028.
The Shenzhen city government lists the APEC leaders’ meeting for Wednesday, 18 November, to Thursday, 19 November. For earlier coverage, see Mexico geopolitics and China and Mexico’s 50% Chinese car tariff.
What It Means for US Readers
US companies with plants or suppliers in Mexico now hear Washington call Chinese investment there a security issue. No new rule, tariff or sanction was announced on Wednesday.
For travellers and investors nothing changes on the ground, because the speech states a position and not a policy. Earlier Sheinbaum-Johnson talks are in this report and this follow-up; see also the Mexico hub.
What Is Not Known
The remarks are known from summaries of the speech, and no full transcript was found. It is not known which companies Johnson had in mind, or what he meant by backing firms that cost China money.
No Chinese or Mexican government response had been found by Thursday morning, 29 October. No evidence was offered in the summaries for the claim that China benefits from instability, so it remains Johnson’s assertion.
What Comes Next
Sheinbaum could be asked about the remarks at her next morning press conference, and China’s embassy may respond. The next fixed date is the APEC leaders’ meeting in Shenzhen on 18 to 19 November.
The speech does not mean new US action against Chinese firms in Mexico. Any such step would need a separate announcement by the US or Mexican government.
