Apparently the chinese government is now requiring hugh income tax payments from these companies. Although CXDC made twice the profit in the last quarter (ending Dec.31)compared to the previous quarter(ending Sept.30),they paid 75% of that profit to income tax compared to 1% paid to income tax previously. So although they made twice the profit,the net after taxes was only 1/2 of the previous quarter. Check the latest financial filing from April 13.
