Mexico’s president, Claudia Sheinbaum, has said repeatedly that she approaches Donald Trump with cabeza fría(冷静的头脑（西班牙语）) (a cool head). Her strategy, shrugging off his rhetoric(花言巧语，言辞) while quickly meeting his demands, has won her many fans, including in the White House. Mr Trump has called her “terrific” and “elegant”.
墨西哥总统克劳迪娅·辛鲍姆多次表示，她以“冷静头脑”应对唐纳德·特朗普。她的策略是：对特朗普的言论不予理会，同时迅速满足其要求，这为她赢得了许多粉丝，包括白宫内部人士。特朗普称她“很棒”和“优雅”。
Yet she has not used the phrase since March. Tensions with the United States have been growing over security, migration and trade. “This is one of the most difficult years in the last hundred of the Mexico-US relationship,” says Rafael Fernández de Castro of the University of California, San Diego.(这是美墨关系近一百年来最艰难的年份之一。) Ms Sheinbaum’s rhetoric has shifted from stoic(坚忍的，隐忍的) to defiant(对抗的，挑衅的).
然而，自3月以来，她再未使用过这个短语。美墨之间在安全、移民和贸易问题上的紧张关系不断加剧。加州大学圣迭戈分校的拉斐尔·费尔南德斯·德卡斯特罗表示：“这是美墨关系近一百年来最艰难的年份之一。”辛鲍姆的言辞已从隐忍转向对抗。
The biggest clash(冲突，矛盾) is over security. The United States is no longer just asking Ms Sheinbaum to crack down on(严厉打击，镇压) drug gangs; it is pursuing her allies. In April the Trump administration indict(起诉，控告)ed the then governor of Sinaloa, Rubén Rocha Moya, on charges including drug-trafficking. Mr Rocha Moya, who denies wrongdoing, is close to Andrés Manuel López Obrador, the founder of Morena(墨西哥国家复兴运动党), Ms Sheinbaum’s party. More than 50 Morena politicians have had their American visas revoke(吊销，撤销)d, according to Reuters, a news service.
最大的冲突在于安全问题。美国不再只是要求辛鲍姆打击贩毒集团，而是开始追究她的盟友。4月，特朗普政府起诉了时任锡那罗亚州州长鲁本·罗查·莫亚，罪名包括贩毒等。罗查·莫亚否认不当行为，他与莫雷纳党创始人安德烈斯·曼努埃尔·洛佩斯·奥夫拉多尔关系密切，莫雷纳党是辛鲍姆所在的政党。据路透社报道，已有50多名莫雷纳党政治人物的美国签证被吊销。
