Note that this is not a complete sentence, There is no finite verb.

It sounds like a headline.

Indeed, it is a headline from a local newspaper. The preposition used by the paper is 'over'.

tamguatlayThe preposition used by the paper is 'over'.

Sub-editors often choose words depending to the space available, Had the country been Germany (seven letters) rather than China (five letters) , they might have chosen by.

Thanks, fivejedjon.

But if 'over' is the wrong preposition, why did they use it? It makes no sense to me.

I don't agree that "over" is the wrong preposition.

I see little difference in the context you cite between "in" and "over."
