Washington (AFP) - President Joe Biden and Indian Prime Minister Narendra Modi will hold a virtual summit Monday, clouded by US frustration over New Delhi's neutral stance on Russia's invasion of Ukraine.
The South Asian nation has tried to walk a tightrope between maintaining relations with the West and avoiding alienating Russia, and has not imposed sanctions over the war.
New Delhi has raised concerns in Washington in particular by continuing to buy Russian oil and gas, despite pressure from Biden for world leaders to take a hard line against Moscow.
India said ahead of the talks the meeting would be about strengthening the allies' "comprehensive global strategic partnership," while Washington spotlighted "Russia's brutal war against Ukraine and mitigating its destabilizing impact."
The more pointed US statement suggested that a resolute Biden will press Modi to take a stronger line on Moscow during the call, which takes place at 11:00am (1500 GMT).
The state-run Indian Oil Corp. has bought at least three million barrels of crude from Russia since the start of the invasion on February 24, in defiance of an embargo by Western nations.
Biden and Modi failed to reach a joint condemnation of the Russian invasion when they last spoke in early March at a meeting of the so-called "Quad" alliance of the United States, India, Australia and Japan.
New Delhi abstained when the UN General Assembly voted last week to suspend Russia from its seat on the 47-member Human Rights Council over allegations that Russian soldiers in Ukraine engaged in war crimes.
The United States has already warned that any country that actively helps Russia to circumvent international sanctions will suffer "consequences."
Yet this has not deterred India from working with Russia on a rupee-ruble payment mechanism to circumvent banking sanctions, while taking advantage of discounted oil prices offered by Russian producers.
Biden said on March 21 that India was an exception among Washington's allies with its "somewhat shaky" response to the Russian offensive.
In the Cold War, officially non-aligned India leaned towards the Soviet Union -- in part due to US support for arch-rival Pakistan -- buying its first Russian MiG-21 fighter jets in 1962.
According to experts, Russia remains India's biggest supplier of major arms and India is also Russia's largest customer.
Russian Foreign Minister Sergei Lavrov, who met with Modi in New Delhi in early April, lauded India for its approach to the conflict, and in particular for judging "the situation in its entirety, not just in a one-sided way."
Biden and Modi are also expected to talk about ending the Covid-19 pandemic, countering climate change, and bolstering security and democracy in the Asia-Pacific region, where India is seen as a critical counterweight to growing Chinese power.
The last confrontation between the Chinese and Indian militaries on the Line of Control, on the border of Tibet and the Indian region of Ladakh, flared up as recently as June 2020.
Ukraine and China are also expected to be on the agenda when the US and Indian foreign and defense ministers hold the annual "2+2 Dialogue," launched in 2018 to deepen cooperation between the two countries.
The two sides are aiming eventually to take bilateral trade from the $113 billion registered in 2021 to $500 billion.
But another point of contention is likely to be India's purchase of Russia's S-400 missile defense system, which contravenes a US prohibition on countries from signing defense deals with Russia, Iran or North Korea.
The US sanctioned China in 2018 for buying the system but has not committed to doing the same for India.
