Why is PDG set up to be exclusively Dutch?

In the first place, bi-lateral cooperation is an important and effective means to develop economic cooperation. The Russian Federation are actively using this route, in particular in the energy sector.
In the second place, Dutch know-how and expertise is in global context very extensive and advanced with respect to the specific challenges to work in such a complex environment of deltaic low-lands and shallow water seas and estuaries, as one finds on the Yamal Peninsula and in the bordering Kara Sea.
