Summary Box: Sands sued in Macau for $375 million

THE CLAIM: Asian American Entertainment Corp., controlled by Shi Sheng Hao, is suing Las Vegas Sands Corp. for $375 million in a Macau court over how it won a lucrative gaming license there. Asian American says Sands' billionaire CEO, Sheldon Adelson, went behind its back to bid with a different company.

THE BACKSTORY: Hao says he teamed with Sands in October 2001 to build a Venice-themed resort. Sands instead partnered with Hong Kong-based Galaxy Entertainment to open the Venetian Macao in 2007.

LITIGATION GALORE: A Nevada court dismissed an earlier lawsuit from Hao. Sands settled another lawsuit in 2009 over its entry to Macau. And a separate claim by Hong Kong businessman Richard Suen remains in play.
