This would be hard to say, due to the lack of any policy guidelines and reference material. Please note that in early 2019, several years after the investor program has been implemented in the Netherlands, less than a handful of people are actually holding a resident permit based on this immigration scheme. As for your question, I believe that the agency favors investors who add specific knowledge, networks or clients by bringing these to the Netherlands. A network only in Vietnam would not contribute to the Dutch economy, unless your initiative for investment is opening up this network to (business partners or other parties in) the Netherlands.
