President Joe Biden will "build on the commonalities" he shares with Indian Prime Minister Narendra Modi during talks on Tuesday despite differences on issues including Russia, according to a senior U.S. administration official.

Modi and Biden will join leaders from Australia and Japan in Tokyo for a "Quad" summit in addition to holding their own meeting on the sidelines.

India frustrated the United States with what Washington regarded as a lack of support for U.S.-led sanctions and condemnation of Russia's invasion of Ukraine.

But Western officials decided to push Modi on the issue gently and privately, seeking instead to emphasize their shared views on China, which Washington views as a bigger long-term challenge than Russia.

India has developed close ties with Washington in recent years and is a vital part of the Quad grouping aimed at pushing back against China.

But it has a long-standing relationship with Moscow, which remains a major supplier of its defense equipment and oil supplies. India abstained in U.N. Security Council votes on the issue, though it did raise concerns about some killings of civilians in Ukraine.

"The president is very aware that countries have their own histories, they have their own interests, they have their own outlooks, and the idea is to build on commonalities," said a U.S. official who briefed reporters and declined to be named.

One key question for Washington going into the Quad meeting is how to wean India off Russian-supplied military equipment and whether to provide defense aid and other support to India to accelerate that transition.

The United States is considering "investment support" of $4 billion for India on top of billions of dollars extended earlier, New Delhi said on Monday after the two sides signed an agreement for COVID-19 vaccine manufacturing, healthcare, renewable energy, financial inclusion and infrastructure.

India also joined the United States and 11 other countries in Washington-led economic talks called the Indo-Pacific Economic Framework for Prosperity (IPEF).

Though Taiwan was not an official item on the Quad agenda, another U.S. official said, it was expected to be a key topic that comes up when the four leaders meet a day after Biden broke with convention and volunteered U.S. military support for the self-governed island claimed by China.
