'international markets' vs 'the international market'?


Please consider the following sentence:

Nowadays, advertising and marketing are no longer limited to the national scope but are widely applied in international markets.

I use ‘international markets’ instead of ‘the international market’, because I think there is basically no such a thing as an international market, but it is actually made up of many national markets. what do you think?

Many thanks.

Doesn’t your logic mean that you cannot write ‘international’ there at all (because they are national)?

Personally, I wouldn’t be concerned with’ international markets/the international market’ as much as I would with ‘the national scope’.
