The APEC That Could've Been
The APEC That Could've Been
Jason Lomberg, North American Editor, PSD

The worst collateral damage of COVID-19 is the decimation of global commerce, and trade shows have been hit especially hard – tough to practice “social distancing” with a few thousand people (or more) clustered together. And one of the most unfortunate victims of this new, quarantined reality was the 2020 Ap
