突发特讯！中加签协议，特朗普表态：对加拿大来说，是件好事情，少见措辞引发国际舆论

Group 1 - The signing of the "China-Canada Economic and Trade Cooperation Roadmap" by Canadian Prime Minister Carney in Beijing has elicited a surprisingly calm response from the White House, indicating a strategic calculation behind President Trump's seemingly casual remarks [1] - Recent tensions in US-Canada relations, including steel tariffs and automotive industry disputes, have led to a shift in Canadian public opinion, with 59% of Canadians viewing the US as a primary threat, while only 17% hold a negative view of China [3] - Trump's contradictory stance, promising to lower tariffs on Canada while simultaneously expressing that Americans do not want Canadian-made cars, reveals anxiety over US control of the North American supply chain as Canada begins to introduce 49,000 Chinese electric vehicles [3] Group 2 - The Canada-China agreement marks a turning point in Canadian foreign policy, with Carney's statement that "China is more stable and predictable than the US" interpreted as both support for China and a critique of the US [5] - A solid public opinion foundation supports this shift, with 54% of Canadians favoring trade agreements with China and over 60% supporting the complete removal of tariffs on Chinese electric vehicles [5] - The US may be allowing Canada to explore the Chinese market to alleviate anti-American sentiments among allies while simultaneously gathering data on the Chinese electric vehicle industry for future technological restrictions [5] Group 3 - The signing of eight agreements covering energy and food security between Canada and China is seen as a potential disruption to the North American supply chain, raising concerns about whether Mexico or the EU might follow suit [7] - Trump's nonchalant approval of the Canada-China agreement is perceived as a calm before a potential storm, indicating a strategic ambiguity that allows for future tariff increases while observing the outcomes of Canada-China cooperation [7] - As Canadian public support for China exceeds 50%, and with the competitive pricing of Chinese electric vehicles, the US may need to reconsider the impact of tariffs on its own allies [7] Group 4 - The apparent thaw in Canada-China relations may signal the beginning of a new phase in geopolitical competition, rather than a resolution of existing tensions, suggesting that the handshake between the two nations is just the prelude to a new round of negotiations [9]
