The closure disrupts a corridor which normally accounts for 90% of rail freight traffic between China and the EU, according to data published by Politico. The decision to close the border is "related to the Russian-Belarusian 'Zapad-2025' exercises," the Polish foreign affairs ministry has said in a statement. Warsaw described the maneuvers as "very aggressive" and conducted "very close to the Polish border." The border closure has disrupted a vital rail corridor which normally accounts for approximately €25 billion per year in freight traffic between China and the EU. However, Sikorski stressed that "the logic of trade" was being replaced by "the logic of security," Politico reported, citing Polish foreign affairs spokesman Pawel Wronski.
