Are there any faults in this sentence?

the unocal affair is related to CNOOC Limited which Chinese oil company’s intention of acquisition of a major America energy producer which is Unocal corporation.

I’m afraid there are. I can’t figure out what you’re trying to say well enough to be absolutely sure I’m helping you put it right, but possibly something like:

The ‘Unocal Affair’ relates to the unsuccessful attempt by the Chinese oil company, CNOOC Limited, to acquire Unocal, a major American energy producer.
