      "Negotiators returned to the table this week after a two-month pause in talks over cross-border trade rules. Reuters reported the earlier pause followed a dispute over proposed tariff timelines, while the Associated Press notes that both delegations have since dropped their public objections to the original framework.\n\nThe Guardian's coverage adds that a signing event is tentatively planned for next week, pending final sign-off from both finance ministries. The Washington Post, citing a senior trade official, describes the remaining disagreements as procedural rather than substantive.",
