India vowed on Thursday to protect its labour-intensive agriculture sector, a central sticking point in bogged-down trade talks with the U.S., as Washington threatened 25% tariffs, triggering outrage from the opposition and a slump in the rupee.

US President Donald Trump's decision to impose 25% tariffs on goods imported from India could hit the country's growth prospects, experts say. It is unclear how big the hit could be, given that Trump has announced an unspecified penalty in addition to the 25% tariff rate.
