特朗普总统周二表示，他已暂停原定于周三生效的一系列加拿大商品50%关税。
特朗普在Truth Social的帖子中称：“我已暂停对加拿大征收50%关税，该关税原定于明天上午生效，暂停期限为三天。此举基于美加两国已达成一项协议，仅待文件最终敲定！”
周一，加拿大总理马克·卡尼对记者表示，美加两国正在“进行谈判”。
“谈判非常激烈且微妙。现在不是公开谈论谈判的时候，”卡尼周一用法语对记者说道。
这50%的关税将影响价值200亿美元的加拿大产品，涵盖从曲棍球棒到压舌板等品类。
但此次关税的政治影响可能远超经济影响。加拿大曾威胁将对美国新关税采取报复性征税措施，这将加剧两国间的贸易争端——去年两国双向商品和服务贸易额达8800亿美元。
加拿大官员周二晚间未立即回应美联社的置评请求。
卡尼的办公室表示，过去两天里卡尼与特朗普已进行过两次电话会谈，讨论正在进行的谈判，其中包括周二下午的一次通话，这凸显了双方在最后一刻推动达成协议的努力。
在上月宣布关税计划时，白宫指责加拿大采取了“不合理、不平等且具有歧视性的行动”，对特定美国商品征收关税或实施进口限制，其中包括特朗普去年对加拿大征收首轮关税后加拿大出台的相关措施。
两国都有理由避免局势升级。去年加拿大近72%的商品出口都流向美国。而在11月的中期选举前征收高额新关税，特朗普政府将面临风险：关税成本由美国进口商承担，他们可能会通过抬高价格将成本转嫁给消费者。美国选民本已对高生活成本感到不满。
“我认为双方都不希望这些关税正式生效，”金斯顿·斯伯丁律师事务所合伙人、前美国贸易官员瑞安·马耶鲁斯在关税暂停消息公布前说道，“双方都有强烈的意愿寻求一条‘脱身之路’。”
美国是加拿大的第二大贸易伙伴，仅次于墨西哥。特朗普政府目前对加拿大商品征收10%的关税，但由于大多数加拿大进口商品符合美墨加协定（USMCA）的要求，可豁免关税。该协定是特朗普第一任期内签署的贸易协议。
特朗普与加拿大在贸易、北约、底特律地区桥梁争端以及他威胁将加拿大变为美国第51个州等问题上关系紧张。
特朗普将关税作为其第二任期经济议程的核心。去年，他对几乎所有国家征收了两位数的进口税，理由是长期存在的美国贸易逆差构成国家紧急状态。美国最高法院今年2月裁定特朗普越权，推翻了这些关税，并为联邦政府向进口商退还税款铺平了道路。
因此特朗普一直在寻求其他合法权限来征收关税。
为了对加拿大加征关税，他援引了大萧条时期的1930年关税法案第338条，威胁对占加拿大对美出口约5%的产品征收50%的关税。
近一个世纪前，在美国和全球经济陷入崩溃之际，美国国会通过了1930年关税法案，对全球进口商品征税。该法案以其国会提案人命名为《斯穆特-霍利关税法》，在经济学家和历史学家中臭名昭著，因其限制了世界贸易并加剧了大萧条的影响。
第338条关税此前从未被使用过。
该条款授权总统对歧视美国企业的国家征收最高50%的进口关税，无需开展调查来为征税正名，也未规定关税的有效期限。
美国目前正在重新谈判美墨加协定——特朗普在第一任期内强行迫使美国邻国接受了该协定。威胁动用第338条关税，为美国向渥太华寻求新的让步提供了筹码。

Trump says he paused 50% tariffs on some Canadian goods as deal being finalized

President Trump said Tuesday he has paused the 50% tariffs on a range of Canadian goods that were set to take effect Wednesday.
“I have paused the 50% Tariffs against Canada, that were scheduled to kick in tomorrow morning for a three day period, based on the fact that Canada and the U.S.A., subject to the finalization of documents, have a DEAL!” Mr. Trump said in the Truth Social post.
On Monday, Canadian Prime Minister Mark Carney told reporters that the U.S. and Canada were “negotiating.”
“The negotiations are very intense and delicate. This is not the time to talk about negotiations in public,” Carney told reporters Monday, speaking in French.
The 50% tariffs would affect $20 billion worth of Canadian products, ranging from hockey sticks to tongue depressors.
But the political impact would likely have been bigger than the economic one. Canada had threatened to retaliate against any new tariffs with levies of its own, aggravating a trade fight between countries that sold each other $880 billion worth of goods and services last year.
Canadian officials did not immediately respond to requests for comment from The Associated Press Tuesday night.
Carney and Mr. Trump had spoken twice by phone in the past two days about the ongoing negotiations, including a call Tuesday afternoon, Carney’s office said, underscoring the last-minute push for a deal.
In announcing the tariffs last month, the White House accused Canada of taking “unreasonable, unequal, and discriminatory actions” by imposing tariffs or import restrictions on certain American goods, including measures introduced after Mr. Trump’s initial round of tariffs on Canada last year.
Both countries had reason to step back from the brink. Nearly72% of Canada’s goods exports last year went to the United States. And the Trump administration would be taking a risk by imposing a hefty new tariff — paid by U.S. importers who try to pass along the cost to consumers via higher prices — ahead of November’s midterm elections. U.S. voters are already frustrated with the high cost of living.
“I don’t think either side really wants these tariffs to come into effect,” Ryan Majerus, a partner at King & Spalding and a former U.S. trade official, said before the delay was announced. “There’s a pretty strong push on both sides to find an off-ramp here.”
The Trump administration currently imposes a 10% tariff on goods from Canada, the U.S.’s second-largest trading partner after Mexico, though most Canadian imports are exempt because they comply with the U.S.-Mexico-Canada Agreement, a trade deal signed during Mr. Trump’s first term.
Mr. Trump has had a tense relationship with Canada due to trade, NATO, a dispute over aDetroit-area bridgeand his threats to make Canada the U.S.’ 51st state.
The president has made tariffs the centerpiece of his second-term economic agenda. Last year, he imposed double-digit import taxes on almost every country, justifying them by declaring the longstanding U.S. trade deficit a national emergency. The Supreme Court in February ruled that he’d overstepped his authority, striking down those tariffs and setting the stage for the federal government to pay refunds to importers.
So Mr. Trump has looked for other legal authority to impose tariffs.
To hit Canada, he reached back to the Great Depression, invoking Section 338 of the Tariff Act of 1930 to threaten 50% tariffs on products that account for about 5% of Canadian exports to the United States.
Nearly a century ago, with the U.S. and world economies in collapse, Congress passed the 1930 tariff law, imposing taxes on imports from around the world. Known as the Smoot-Hawley tariffs, named for their congressional sponsors, they are notorious among economists and historians for limiting world commerce and making the Great Depression worse.
Section 338 tariffs have never been used before.
Section 338 authorizes the president to impose tariffs of up to 50% on imports from countries that have discriminated against U.S. businesses. No investigation is required to justify the levies. Nor is there any limit on how long the tariffs can stay in place.
The U.S. is renegotiating a North American trade pact — the US-Mexico-Canada Agreement — that Mr. Trump strong-armed America’s neighbors into accepting in his first term. The threat of Section 338 tariffs gives the U.S. leverage to seek fresh concessions from Ottawa.
