REUTERS/Chen Lin/File PhotoJuly 17 (Reuters) - Chinese e-retailer Temu has filed a new lawsuit accusing rival Shein of violating U.S. antitrust law in its dealings with clothing manufacturers, escalating a legal clash for dominance in the fast-fashion market. Temu, represented by prominent U.S. law firm Boies Schiller Flexner, filed the new case on Friday in Boston federal court. The two companies are already embroiled in litigation in Chicago federal court, where Shein has alleged Temu worked with influencers to disparage Shein on social media. Temu's complaint alleged Shein "forces manufacturers to sign loyalty oaths certifying that they will not do business with Temu." A spokesperson for Shein on Monday said Temu's lawsuit was "without merit and we will vigorously defend ourselves."
