Cornelis Haga was sent to Stockholm; and from this time forward a close intimacy was established between Sweden and the States.

The seaport of Gotheborg, just outside the entrance to the Sound, was founded by a body of Dutch colonists under a certain Abraham Cabelliau, an Amsterdam merchant, and continued to be for years practically a Dutch town.
Scarcely less important was the enterprise shown in the establishment of friendly relations with distant Russia.

Balthazar de Moucheron established a Dutch factory at Archangel so early as 1584; and a growing trade sprang up with Russia by way of the White Sea, at first in rivalry with the English Muscovy Company.

But a Dutch merchant, by name Isaac Massa, having succeeded in gaining the ear and confidence of the Tsar, Russian commerce gradually became a Dutch monopoly.

In 1614 a Muscovite embassy conducted by Massa came to the Hague, and access to the interior of Russia was opened to the traders of Holland and to them only.
In the Mediterranean no less foresight and dexterity was shown in forwarding the interests of the States.
