We can agree to disagree on hegemonic power being a bigger deal than dictators. But regardless, saying China is insular is ridiculous. They have a very public plan to expand their hegemony by taking over the infrastructure of other nations by way of “developmental loans”.
That article says the exact opposite of what you are claiming. This is the lede paragraph:
"In December 2018, a leaked letter from the Kenyan auditor-general’s office sparked a rumour that Kenya had staked its bustling Mombasa Port as collateral for the Chinese-financed Standard Gauge Railway. Our new research shows why the collateral rumour is wrong."
IMF forces countries to adopt austerity politics[1], causing lower economic activity and often leading to economy shrinkage[2], and forces countries to open their markets to foreign capital, which leads to surplus extraction abroad. Both of those measures lead to impoverishing the country that is taking the loan.
