India's Mukesh Ambani family is the richest in Asia as its net worth rose $19 billion to $44.8 billion, toppling the Lees of the Samsung empire, to claim the numero uno position, Forbes said.
Despite dropping to the second spot, Korea's Lee family still saw its wealth soar by 11.2 billion to $40.8 billion this year as shares of Samsung Electronics moved up 75 per cent over the past year.
