Li Ka-Shing, Asia's richest man, is basing his corporate empire in the Cayman Islands.

Asia's richest man just saw his wealth leap again.

Shares in companies owned by Hong Kong tycoon Li Ka-Shing soared Monday after he announced plans to restructure his massive empire and move it to the Cayman Islands.

Property company Cheung Kong (CHEUF) jumped nearly 15%, while investment holding firm Hutchison Whampoa (HUWHF) climbed almost 13% in Hong Kong trading. Both are controlled by Li, 86, worth an estimated $33 billion, according to the Hurun report.

Li's restructuring plans were announced late on Friday. They will split his assets into a new pair of companies. All real estate holdings will be grouped under CK Property, while other businesses including energy, retail, utilities and telecoms will be placed under CKH Holdings.

The new companies will be registered and traded in Hong Kong. But they'll both have their base in the Cayman Islands, a notoriously opaque tax haven.

Li called the restructuring a "watershed event," and said it will now be easier for investors to decide which businesses they want to buy into, according to a statement.

The overhaul took analysts by surprise, but their reactions have been positive.

The restructuring will streamline and simplify the current structure, under which Cheung Kong holds nearly 50% of Hutchison, wrote Wee Liat Lee and Patrick Wong of BNP Paribas in a note.

Li's assets span numerous industries, from property to utilities. His name, empire and influence are well-known to residents of Hong Kong.
