<h1>US president skips Quad summit as executive ties with India sour over mediation claims, tariffs, and stalled cooperation</h1> A major news report states that the US president no longer plans to attend the Quad Summit in India this fall, citing a deterioration in executive-level relations between the United States and India. The breakdown is linked to disputed claims about US mediation in a recent India-Pakistan military escalation, repeated public assertions by the US president, and retaliatory US tariffs on Indian oil imports. The dispute involves refusal by the Indian prime minister to engage on a proposed Nobel nomination and to respond to outreach on trade, raising risks to bilateral trade negotiations, diplomatic cooperation within the Quad, and potential policy escalation through tariffs or reciprocal measures.
