The 2026 World Cup was marked by serious diplomatic conflicts between Iran, Mexico, and Ecuador, as well as the introduction of new disciplinary rules by FIFA.

2026年世界盃的特點是伊朗、墨西哥與厄瓜多之間存在嚴重的外交衝突，以及FIFA引入了新的紀律規則。

The Iranian national team, Team Melli, faced many travel and logistical problems caused by United States authorities. The Department of Homeland Security restricted visas for important staff and forced the team to stay in Tijuana, Mexico, instead of inside the U.S. Secretary Markwayne Mullin justified these actions by claiming the team had links to the Revolutionary Guard. Furthermore, Secretary Mullin publicly expressed that he was happy when Iran was knocked out of the tournament. In response, the Iranian Football Federation asserted that these actions violated international standards. At the same time, the team used the event to highlight a deadly missile strike on a primary school, which they blamed on U.S. forces.

伊朗國家隊（Team Melli）面臨許多由美國當局引起的交通與物流問題。國土安全部限制了重要職員的簽證，強迫球隊留在墨西哥的蒂華納，而非留在美國境內。部長 Markwayne Mullin 以球隊與革命衛隊有聯繫為由，證明這些行動是合理的。此外，Mullin 部長在公開場合表示，當伊朗被淘汰出局時他感到很高興。作為回應，伊朗足協聲明這些行動違反了國際標準。同時，球隊利用這次活動來強調一次對小學的致命導彈襲擊，他們將責任歸咎於美國軍隊。

Similarly, there was strong political tension between Mexico and Ecuador. Their match took place while the two countries had no diplomatic relations, following a raid on the Mexican embassy in Quito in April 2024. This conflict was visible in the stadium, where Mexican fans used homophobic chants and caused disturbances at the Ecuadorian team's hotel. While Ecuadorian President Daniel Noboa suggested that relations could improve, Mexican President Claudia Sheinbaum emphasized that no diplomatic talks would happen until the tournament ended.

同樣地，墨西哥與厄瓜多之間也存在強烈的政治緊張局勢。他們的比賽在兩國沒有外交關係的情況下進行，此前於 2024 年 4 月在基多的墨西哥大使館遭到突擊搜查。這場衝突在體育場內顯而易見，墨西哥球迷使用了恐同口號，並在厄瓜多球隊的酒店造成騷亂。雖然厄瓜多總統 Daniel Noboa 建議關係可以改善，但墨西哥總統 Claudia Sheinbaum 強調，在賽事結束前不會進行任何外交談判。

Additionally, the tournament introduced a new rule from the International Football Association Board (IFAB) that stops players from covering their mouths during arguments. This rule was created to prevent players from using hidden abusive language. Consequently, players Piero Hincapié from Ecuador and Miguel Almirón from Paraguay were sent off. This regulation was caused by a previous incident involving Gianluca Prestianni and Vinicius Jr, leading FIFA President Gianni Infantino to argue that such gestures should be seen as misconduct.

此外，賽事引入了國際足球理事會（IFAB）的一項新規則，禁止球員在爭論時遮住口部。這項規則旨在防止球員使用隱蔽的侮辱性語言。因此，厄瓜多的 Piero Hincapié 和巴拉圭的 Miguel Almirón 被驅逐出場。這項規例是由於先前涉及 Gianluca Prestianni 和 Vinicius Jr 的事件引起，導致 FIFA 主席 Gianni Infantino 主張此類動作應被視為不當行為。

The tournament ended with the elimination of Iran and Ecuador, leaving behind a history of damaged international relations and stricter rules for player behavior.

賽事在伊朗與厄瓜多被淘汰後結束，留下了一段外交關係受損的歷史，以及對球員行為更嚴格的規則。
