India has put on hold plans to procure new US weapons and aircraft due to tariffs imposed by President Donald Trump, which have raised duties on Indian exports to 50% - the highest of any US trading partner. Defence Minister Rajnath Singh's trip to Washington for an announcement on defence purchases has been cancelled. The decision comes after Trump imposed additional 25% tariff on Indian goods as punishment for Delhi's purchases of Russian oil, fueling Russia's invasion of Ukraine. India had planned to send Singh to announce the purchase of six Boeing P8I reconnaissance aircraft and support systems for the Indian Navy in a $3.6 billion deal. The pause in defence purchases is seen as a sign of discontent between the two countries, with India claiming unfair targeting by Washington.
