Hanoi is in similar talks with multiple arms suppliers, including the United States. In recent weeks, Vietnam has engaged in several high-level defence meetings with top Russian officials.
The U.S.- Vietnam upgrade will include a security dimension, Jon Finer, the U.S. principal deputy national security adviser, told reporters on Sunday, while on the plane with Biden to Vietnam from a Group of 20 summit in India.
He said he had no arms deals to announce at this stage but stressed that the U.S. and its partners could offer Vietnam help to diversify away from Russian military supplies, an offer which he said Vietnam was receptive to.
That would help Vietnam reduce military reliance on Moscow, "a relationship we think they are increasingly uncomfortable with," Finer said.
CHIPS, RARE EARTHS
Biden's visit comes as bilateral trade and investment ties are growing and a long-simmering territorial dispute between Vietnam and China heats up in the South China Sea.
Vietnam Airlines (HVN.HM) is expected to sign an initial agreement to buy about 50 Boeing (BA.N) 737 Max jets in a deal valued at $10 billion, timed to the trip.
Highlighting Vietnam's growing importance as a "friendshoring" destination for U.S. technology companies, executives from Google (GOOGL.O), Intel (INTC.O), Amkor (AMKR.O), Marvell (MRVL.O), GlobalFoundries (GFS.O) and Boeing (BA.N) are expected to meet on Monday with Vietnamese tech executives and Secretary of State Antony Blinken in Hanoi.
Still, semiconductors are the centrepiece of an action plan adopted during Biden's visit, U.S. officials said.
Besides possible announcements by U.S. corporations, it is unclear what else the the partnership could mean. The US government has $100 million a year for five years available under the CHIPS Act to support semiconductor supply chains globally. A large part of it could go to Vietnam, officials said.
More support to train skilled workers is also part of the deal, as Vietnam faces a major shortage of engineers in the chips sector.
Another key issue is strengthening supply chains of critical minerals, especially rare earths, of which Vietnam has the world's largest deposits after China, according to U.S. estimates, officials said.
Two people familiar with the plans said an agreement on rare earths was expected during Biden's visit, which ends on Monday when he flies back to America.
Details, however, are scant. Past attempts by U.S. companies to partner with Vietnamese rare earth firms have not succeeded, according to a person involved in one recent plan.
Human rights remain a controversial issue, with U.S. officials regularly criticising Hanoi for jailing activists and limiting freedom of expression. Vietnam may show goodwill, with diplomats suggesting activists could be freed.
