New Delhi: US President Joe Biden said on Friday said that he shared a "very good" relationship with India and has visited the country twice, as he left on a weekend trip to his home in Delaware.


The president told reporters at the White House that he had been briefed on the three Americans who have been missing in Ukraine.


"I don’t know where they are. But I want to reiterate. Americans should not be going to Ukraine. I say it again. Americans should not be going to Ukraine,” he said.


In response to a question on India, Biden said, "I have been to India twice and will be back. My relationship with (India is) very good".


Biden's remarks came a day after State Department spokesperson Ned Price said the US is there for India and reiterated that New Delhi's relationship with Moscow developed over several decades when Washington was "not prepared or able to be a partner of choice" for the Indian government.


Price was responding to a question on whether the US was talking with the Indian authorities as India and other Asian nations are becoming an increasingly vital source of oil revenues for sanctions-hit Russia, despite strong pressure from America.


"We have had a number of discussions with our Indian partners, and the point that we have made is that every country is going to have a different relationship with Moscow," Price told reporters at his daily news conference on Thursday.


Russia has overtaken Saudi Arabia to become India's second-biggest supplier of oil behind Iraq as refiners snap up Russian crude available at a deep discount following the war in Ukraine, industry data showed recently.


India, the world's third-biggest oil-importing and consuming nation, has long defended purchases of crude oil from Russia following President Vladimir Putin ordering the invasion of Ukraine. The oil ministry had last month stated that "energy purchases from Russia remain minuscule in comparison to India's total consumption." Price said India's relationship with Russia developed over several decades.


"It developed over the course of decades at a time when the United States was not prepared or able to be a partner of choice for the Indian government," he said.


"That has changed. This is a legacy of a bipartisan tradition now that has been the case for more than two decades. It goes back really to the Clinton administration, certainly to the George W Bush administration, where the United States has sought a partnership with India, has sought to be a partner of choice for India, including when it comes to the security realm," he said.


This is not a partnership built in the course of days, weeks, or months, Price said.


"I mentioned before that India's relationship with Russia was built up over the course of many decades, as countries reorient their relationship with Moscow, as we have seen many of them do. This will be a gradual process," he said in response to a question.


"But throughout it all, we have made clear to our Indian partners that we are there for them. We are ready and able, and willing to partner with them. And we've done just that," Price said.


"Of course, we had a '2+2' dialogue with our Indian partners not too long ago. We will see Prime Minister Narendra Modi once again in the context of the I2U2, the arrangement we have with the UAE and Israel, along with India, incorporating India into many of the partnerships we have, including, of course, the Quad," he said.


"And that is a group this administration has sought to revitalise, and it has done so at very high levels," the official added.


To re-energise and revitalise American alliances globally, the US, UAE, India and Israel have formed a new grouping called I2-U2. The four countries in the new grouping will hold their first virtual summit next month.


Quad comprises Japan, India, Australia and the United States.


The four countries in 2017 had given shape to the Quadrilateral coalition to counter China's aggressive behaviour in the Indo-Pacific region.
