Due to the discovery of renormalon cancelation, understanding of the

heavy quark mass and interquark force was improved drastically around 1998. 

I overview what was understood then and theoretical progress that took 

place after it. 

We show how to extract genuine UV part of the leading Wilson coefficient 

in OPE of the static QCD potential and how it improves the theory 

prediction in the range r*Lambda_QCD < 0.8 with regard to lattice 

computations.
