The 25 percent US tariffs likely to be imposed on Indian exports, which is higher than that of many countries in Asia, can wreak havoc on India's economy, analysts said.

US President Donald Trump said on Wednesday that the United States is still negotiating with India on trade.

The government will take "all steps necessary to secure our national interest, as has been the case with other trade agreements, including the latest Comprehensive Economic and Trade Agreement with the UK," the ministry said.

"The tariffs will affect nearly $87 billion worth of goods sold to the US market annually. The US is one of India's largest export destinations."
