Blinken in India for talks dominated by Afghan turmoil, China
US-Indian relations have long been cool but China's growing assertiveness pushed them closer, particularly since deadly clashes last year on the disputed Indo-Chinese Himalayan border.
New Delhi is meanwhile alarmed that a possible Taliban takeover in Afghanistan after the withdrawal of forces will turn the country into a haven for anti-India extremists.
Under Modi, India has made growing use of anti-terrorism legislation and "sedition" laws to arrest people, in what critics say is aimed at silencing dissent. The government denies this.
The Hindu-nationalist government has also brought in legislation that detractors say discriminates against India's 170-million-strong Muslim minority. Modi insists all Indians have equal rights.
