In fact, Ji Chen had provided weapons and gear to Gilder and his team in the Northern Continent, but this didn't impact his sales to the Lienhardt Grand Duchy.
The reason these four countries along the northwest coast of the Midland Sea, including the Lienhardt Grand Duchy, were distinct was due to a colossal mountain range stretching from southeast to northwest, setting them apart from countries like the Maple Principality and the Elven Empire.
So, these four countries were nominally part of the Northern Continent, but geographically, they weren't.
However, Ji Chen was quite pleased with the opportunity to promote products from his own territory.
Thanks to his ongoing "reduce inventory" efforts, the weapons and equipment that the lizardmen had accumulated in warehouses over the years had mostly been depleted in several large-scale exports. The order from the Lienhardt Grand Duchy had also cleared out the last batch of inventory.
