Just remember Trump has the foreign policy knowledge of a drunk at the local bar.
Under his watch China expanded dramatically in Africa and Latin America (infrastructure projects) and squashed democracy in Hong Kong.
He fails to realise what soft power is and how the USA benefitted enormously from programs like peace corps etc. Anywhere the Chinese go they are arrogant and dismissive of the population and hated.
So he's just talking out of his arse like the way faux tough guys do. Yet, you can sane-wash it that if he really considers it dealing with China in third world places then that's actually good.
However, talking about it in an arrogant and dismissive way lowers the USA to the level of China, thus once again unilaterally forfeiting the big advantage the USA has (soft power) over China.
