The annexation of the city had enormous consequences for the Lithuanian economy and foreign relations. The region subsequently accounted for up to 30% of the Lithuania's entire production. Between 70% and 80% of foreign trade passed through Klaipėda. The region, which represented only about 5% of Lithuania's territory, contained a third of its industry. Weimar Germany, under Foreign Minister Gustav Stresemann, maintained normal relations with Lithuania. However, Nazi Germany desired to reacquire the region and tensions rose. Pro-German parties won clear supermajorities in all elections to the Klaipėda Parliament, which often clashed with the Lithuanian-appointed Klaipėda Directorate. Lithuanian efforts to "re-Lithuanize" Prussian Lithuanians by promoting Lithuanian language, culture, education were often met with resistance from the locals. In 1932, a conflict between the Parliament and the Directorate had to be resolved by the Permanent Court of International Justice. In 1934–1935, the Lithuanians attempted to combat increasing Nazi influence in the region by arresting and prosecuting over 120 Nazi activists for the alleged plot to organize an anti-Lithuanian rebellion. Despite rather harsh sentences, the defendants in the so-called Neumann–Sass case were soon released under pressure from Nazi Germany. The extensive autonomy guaranteed by the Klaipėda Convention prevented Lithuania from blocking the growing pro-German attitudes in the region.
