Intense nationalism, for example, can lead to difficulties. Nationalism is the sense of national consciousness that boosts the culture and interests of one country over those of all other countries. Strongly nationalistic countries, such as Iran and New Guinea, often discourage investment by foreign companies. In other, less radical forms of nationalism, the government may take actions to hinder foreign operations. France, for example, requires pop music stations to play at least 40 percent of their songs in French. This law was enacted because the French love American rock and roll. Without airtime, American music sales suffer. In another example of nationalism, U.S.-based PPG made an unsolicited bid to acquire Netherlands-based AzkoNobel NV. There was a chorus of opposition from Dutch politicians to the idea of a foreign takeover of AzkoNobel, the Dutch paint manufacturer. The government warned that it would move to defend AzkoNobel from a hostile takeover attempt. AzkoNobel played up the sentiment, tweeting about its rejection of the hostile takeover with the hashtag #DutchPride.37

Protective tariffs make imported products less attractive to buyers than domestic products. The United States, for instance, has protective tariffs on imported poultry, textiles, sugar, and some types of steel and clothing, and in March of 2018 the Trump administration added tariffs on steel and aluminum from most countries. On the other side of the world, Japan imposes a tariff on U.S. cigarettes that makes them cost 60 percent more than Japanese brands. U.S. tobacco firms believe they could get as much as a third of the Japanese market if there were no tariffs on cigarettes. With tariffs, they have under 2 percent of the market.
