U.S. Secretary of State Mike Pompeo meets Indian Prime Minister Narendra Modi in New Delhi on June 26, 2019.

U.S. Secretary of State Mike Pompeo held meetings in India's capital on Wednesday amid growing tensions over trade and tariffs that has strained the partners' ties.

Pompeo called on India's Prime Minister Narendra Modi on Wednesday morning, and later was meeting his counterpart S. Jaishankar.

India's foreign ministry spokesman Raveesh Kumar said Pompeo and Modi exchanged "views on various aspects of Indo-US relationship."

"Working together to further deepen our strategic partnership," Kumar tweeted.

Pompeo arrived in New Delhi late Tuesday after visiting Saudi Arabia, the United Arab Emirates and Afghanistan on a trip aimed at building a global coalition to counter Iran.

His visit is the first high-level engagement between the two countries since Modi's reelection last month. The countries call each other a strategic partner despite retaliatory tariffs they imposed on some of the other's goods this month.

India imposed tariffs on 28 American products including walnuts and almonds on June 16 in retaliation for the U.S. ending India's preferential trade status on June 1. The Trump administration imposed higher duties on products including aluminum and steel.

The visit also comes ahead of the scheduled meeting between President Donald Trump and Modi on the sidelines of the Group of 20 Summit in Japan later this week.

The two countries' officials are also likely to discuss India's plans to purchase Russia's S-400 air defense system. U.S. has shown reservations about the deal. But still the U.S. has become India's top defense supplier in last two years. India's trade with the U.S. has also seen steady growth at $150 billion annually.

Indian officials say they have little differences with the U.S. over political and strategic issues including on Iran, but they have cautioned the two countries need to be careful on trade and commerce.

India stopped oil purchases from Iran after the U.S. sanctions waiver ran out in May but Indian officials have continued working out for a renewal of the waiver amid escalating tensions between the U.S. and Iran. Indian officials say while they understand the U.S. concerns regarding Iran, their country has taken an economic hit.

Before Pompeo's arrival in India, hundreds of supporters of left-wing groups marched in central New Delhi to protest his visit and denounce American policies in the Middle East. They urged the Indian government not to cut off imports of oil from Iran, as the U.S. has demanded.

Pran Sharma, a protester, said there was a "bigger game" behind "the trade war" between India and the U.S.

"That is the invasion of Iran, for which it (U.S.) is making preparations. How it can get cooperation from India?" he said.
