WASHINGTON - India once united US policymakers like few issues. For nearly three decades, US presidents of both parties courted New Delhi as an emerging ally, politely overlooking disagreements for the sake of larger goals.
Donald Trump has abruptly changed that.
The US administration on Wednesday slapped 50 percent tariffs on many Indian products as Trump seeks to punish India for buying oil from Russia.
India was a Cold War partner of Moscow but since the 1990s US leaders have hoped for a joint front with fellow democracy India in the face of the rise of China, seen by Washington as its top long-term adversary.
In striking timing, Indian Prime Minister Narendra Modi heads to China this weekend, the latest meeting between the world's two most populous nations as they explore areas of common ground.
Trump has accused India of fueling Moscow's deadly attacks on Ukraine by purchasing Russian oil. Trump trade advisor Peter Navarro even called Ukraine "Modi's war" in a Bloomberg TV interview Wednesday.
Yet Trump has refrained from tougher US sanctions on Russia itself, saying he still hopes for a negotiated settlement despite wide pessimism.
"This is not just about tariffs, not just about Russia, not just about oil," said Tanvi Madan of the Brookings Institution.
"There seems to be something broader going on here -- personal on Trump's side, piqued as he may be at India," she said.
"And then on the Indian side, for Modi, it becomes a political issue."
Faltering bromance
Trump and Modi, both right-wing populists, appeared to forge a strong bond during Trump's first term.
In 2020, Trump rejoiced as Modi invited him to inaugurate the world's largest cricket stadium in front more than 120,000 people.
But Trump has since appeared irritated as he seeks credit for what he said was Nobel Prize-worthy diplomacy between Pakistan and India, which struck its neighbor in May in response to a massacre of Indian civilians in divided Kashmir.
