That is really a confusing matter. I have seen both movies, but always with German titles/credits.
The facts I have collected (maybe it is helpful):
Movie 1:
Zen Kwun Do strikes in Paris
Directed by John Liu
With John Liu, Roger Paschy, Alan Chui, Tino Wong, KG Young, Dan Schwarz, Wong Chi-Ming, Siu Tak-Foo, Peng Kang, Lam Gwong-Wing, Chu Siu-Wa, Mau Ging-Shun
Movie 2:
In the Claws of the CIA
Ninja vs (the) CIA
Made in China
Directed by John Liu
With John Liu, Casanova Wong, Roger Paschy, Gam Biu, Christian Anders
Now the only question for me is if "Kung Fu Leung strikes Emanuelle" 艾曼妞火拚功夫良 is the alias of movie 1 or movie 2.
For movie 1 speaks that the HKFA entry with this title
http://ipac.hkfa.lcsd.gov.hk/ipac20/ipa ... ex=FILMBRP
has Alan Chui in the cast. Looks also like the cast at your link at the post above.
That page has a chinese title of CIA:

I don't know if that is helpful.
