evidence: The legion of technology, finance, and media bosses at Mukesh Ambani's three-day bash underscores not just his global influence, but India's growing importance to foreign companies. Ambani, who owns a 42% stake in Reliance Industries, ranks 11th on the Bloomberg Billionaires Index with a $111 billion fortune, just behind Alphabet founders Larry Page and Sergey Brin. He's hosting this weekend's celebration for his youngest son, Anant, and his fiancée, Radhika Merchant. [...] The Ambani pre-wedding event offers a chance to break bread with one of India's most powerful men and his family, rub shoulders with a who's who of industry leaders, discuss and strike local deals, and enjoy what's bound to be one of this year's most extravagant parties.
