NEW DELHI, Jan 5 (Reuters) – The United States could raise tariffs on India if New Delhi doesn’t meet Washington’s demand ​to curb purchases of Russian oil, President Donald Trump told ‌reporters aboard Air Force One.

“Modi is a good guy. He knew I was not ‌happy, and it was important to make me happy,” Trump said on Sunday.

“They do trade, and we can raise tariffs on them very quickly,” Trump said in response to a question on India’s Russian oil ⁠purchases.

India’s commerce ministry did not ‌immediately respond to a request for comment.

The U.S. doubled import tariffs on Indian goods to 50% last year ‍as punishment for its heavy buying of Russian oil. Despite the hefty tariffs, India’s exports to the U.S. leapt in November.

Encouraged by the improved trade ​data, Indian officials have maintained a firm stance against U.S. trade ‌demands, signalling limited flexibility in areas such as agricultural imports, while data shows India’s oil purchases from Russia have declined.

India is asking refiners for weekly disclosures of Russian and U.S. oil purchases, people familiar with the matter told Reuters last week, adding that they expect Russian ⁠crude imports to dip below 1 million ​barrels per day as New Delhi seeks ​to clinch a trade deal with Washington.

Modi has spoken to Trump at least three times over the phone since ‍he imposed tariffs, ⁠but the discussions remain inconclusive.

India’s Commerce Secretary Rajesh Agrawal met U.S. Deputy Trade Representative Rick Switzer to discuss bilateral trade and ⁠economic ties last month in Delhi.
