Searches for anomalous Zt and production provide an excellent probe of flavour-changing top interactions when the energies considered are very large. In this note we estimate the sensitivity to these interactions at the high-luminosity phase of the LHC and a future 100 TeV pp collider (FCC-hh). For the LHC, the expected limits on 
branching ratios from Zt and production will reach the 
level, one order of magnitude better than the existing projections for 
from 
production. For the FCC-hh, the limits on could reach an impressive sensitivity at the 
level, with limits on 
at the level.
