From the above document, On page chapter 12-6, section 16, you're exempted from the 14 ground theory examinations, except for Air Law, HPL and Performance if you meet the following stipulations;
--------
16: Notwithstanding 15, an applicant for a CPL(A) who does not meet any one of the following requirements shall be required to pass the theoretical knowledge examinations:
(a) At least 700 total flying hours as pilot of aeroplanes
(b) At least 200 hours as pilot in command of aeroplanes
(c) At least 10 hours flying cross country at night or by sole reference to instruments
---------
So, if you meet any of the above, then you don't need to do the ground theory exams except for those specified in paragraph 15 (Air Law, HPL and Performance).
And from section paragraph 15, you may be exempted from the Performance exam if you have more than 3000 hours of which 500 hours is on multi-crew type aircraft.
Which leaves only Air Law and HPL exams required for the conversion from a foreign ATPL to a CAAS ATPL, if you meet the above stipulations.
