Is that a dollar in your pocket, or the GDP of Iceland? Mainland China's richest tycoon increases wealth by US$17 billion

Property and entertainment tycoon Wang Jianlin topped mainland rich list this year with his personal wealth ballooning nearly US$17 billion - equivalent to the GDP of Iceland.

Despite slowing economic growth, the total wealth of the mainland's 100 richest people rose 20 per cent from US$376 billion last year to US$450 billion.

Wang, chairman of Dalian Wanda, saw his personal wealth jump from US$13.2 billion to US$30 billion. This was largely driven by the listing of Wanda's commercial property arm in Hong Kong in December and that of its cinema chains in Shenzhen in January.

The GDP of Iceland was US$16.93billion last year.

Alibaba chairman Jack Ma came second, with his wealth growing from US$18.8 billion to US$21.8 billion.
