I think what China is expressing is pretty clear. Of course, it all depends on how you understand the meanings of the words 'intellect' and 'intelligence'.
There are two distincitve and commonly used ways of understanding the term ''intelligence''.
On one side, intelligence means a broad palette of mind abilities that encompass many things such as your efficiency at understanding, learning, reasoning, planning, using language, solving problems, being creative, thinking abstractly, being efficient and ressourceful with your physical environment (spatio-temporal abilities in which athletes exceed), and also, being succesful at social interactions, which implies being sensible to the feelings of others and yourself. Emotional and social intelligence is a crucial part of life and someone who doesn't understand how to appropriately react to emotional and social stimuli is seriously handicapped.
The other common way to understand the term 'intelligence' refers to rational and logic abilities in particular. I'm refering to 'Mensa' type of intelligence. High IQ type of intelligence, where math, logic and pattern recognition is valued.
But a high IQ isn't so desirable if it comes with a social and emotional handicap... Or if it comes with an inability to understand and appreciate music, litterature, painting and all other forms of art.
To sum it up, I think China uses the term 'intelligence' to describe the 1st type of intelligence I described (broad palette of abilities including emotional and social) while the 'intellect' refers to other type of intelligence, the one which focuses on reason and logic.
