After claiming credit for ending India’s military escalation with Pakistan last week, President Trump appeared to rankle New Delhi again on Thursday with comments about high-stakes U.S.-India trade negotiations and Apple’s production of iPhones in the country.

Mr. Trump, speaking to business leaders during his visit to Qatar, said India was nearing “a deal where basically they are willing to literally charge us no tariff,” without offering any details.

In response, S. Jaishankar, India’s foreign minister, was careful not to contradict the president directly. “Trade talks have been going on,” Mr. Jaishankar told the Indian news media, adding that the negotiations “are very intricate” and “nothing is decided until everything is.”
