Sheinbaum Visits Barcelona for Peace Summit Amid Trump Tensions

Mexican President Claudia Sheinbaum has arrived in Barcelona to attend the Global Progressive Mobilisation summit, joining leaders from Brazil, Colombia, Uruguay and Spain in a coordinated effort to defend multilateralism and counter the rise of far-right movements globally.

The summit, which began on Friday, April 17, 2026, is spearheaded by Spanish Prime Minister Pedro Sánchez and Brazilian President Luiz Inácio Lula da Silva, with Sheinbaum confirming her participation amid efforts to rebuild diplomatic ties between Mexico and Spain after years of strain.

Sheinbaum rejected characterisations of the gathering as an “anti-Trump” meeting, stating instead that the objective is to uphold the principle of self-determination for peoples and promote the peaceful resolution of conflicts.

The meetings come as U.S. President Donald Trump’s policies — including cuts to humanitarian aid, military interventions and threats to withdraw from NATO — have disrupted international relations and prompted a reassessment of global alliances among progressive leaders.

Organisers said the summit aims to mobilise advocates of left-wing ideals, culminating in a declaration of common actions on goals ranging from defending democracy to advancing the green transition. A second gathering on Saturday, titled “In defence of democracy,” marks the fourth instalment of a summit series launched by Lula and Sánchez in 2024.

Sheinbaum’s visit represents the first time in eight years that a Mexican president has engaged at this level with Spain, signalling a potential thaw in relations following past disagreements over historical issues related to the colonial period.
