There never was any debt between these two companies. Don't you get it?
Siaf faked having income to build trust in it's claimed business.
They have no money really so they say they give it to TRW to build trust in TRW's claimed assets and business and to avoid having to give money (they don't have really) to shareholders.
TRW has no money or business either, didn't really get any money from Siaf so they can't pay back any money.
Hence the "share dividend" fiasco which was just to fool shareholders getting some value. TRW gave nothing from nothing. Luckily authorities interfered with this BS.
Siaf and TRW are twin scam companies obviously, both having no real business where they are entitled to income. They play these $0,00 NET games to flash big numbers on paper so some misguided investor would buy their shares.
And share printing is the only true business they do.
That's the whole story of Siaf and TRW. It explains management behavior, share price, dilution and everything that's boggling Siaf owner's minds.
