Executives of top tech firms, including Google and Intel, have met with business leaders in Vietnam as part of United States President Joe Biden's landmark visit to the Southeast Asian country. Tech leaders joined Biden and US Secretary of State Antony Blinken on Monday for an "innovation and investment summit" attended by Vietnamese firms, including electric car maker VinFast, internet company VNG and digital wallet provider Momo. Washington and Hanoi are seeking to deepen their cooperation amid shared concerns about China's rising power and influence. The US views Vietnam as a key plank of its plans to reduce its reliance on China for strategic resources, such as semiconductors and rare earth minerals. Vietnam has territorial disputes with Beijing in the South China Sea.
