During the Industrial Revolution, if one European country had access to a valuable resource that another country needed for manufacturing an important product, it would likely create a significant impact on trade between the countries involved.
First, the country that had access to the valuable resource would likely have a significant advantage in manufacturing the product, as they would be able to produce it more efficiently and at a lower cost than the country that did not have access to the resource.
Second, the country that did not have access to the resource would likely need to import it from the country that did, which could result in higher costs and potentially lead to a trade imbalance between the two countries.
Furthermore, if the country that had access to the valuable resource chose to restrict its export or charge a high price for it, it could create tensions and even conflict between the countries, as the country that did not have access to the resource would be at a disadvantage in the global marketplace.
