Chancellor Angela Merkel warned Germans against turning to economic isolationism, saying she’s “not happy” about the possible collapse of the Trans-Pacific Partnership after President-elect Donald Trump said he’ll withdraw from the trade accord. Fresh from announcing she’ll seek a fourth term in next year’s German election, Merkel used a speech to the lower house of parliament in Berlin to acknowledge voters’ anxiety about globalization in Europe and beyond. She expressed concern about election campaigns that are increasingly using “fake websites, bots and trolls” to shape public opinion in ways that conventional politics is unprepared for. “Many people these days are concerned about the stability of the order that we’ve grown so accustomed to,” Merkel said on Wednesday in her first major speech since saying Sunday she’ll run again in 2017. “We need to stand for this together, for multilateralism, on shaping globalization together with others—and I will stand for that.” Without addressing Trump by name, Merkel, the leader of Europe’s biggest economy, defended free trade, including the 12-nation TPP accord. The German leader has made the defense of the global trade agenda a key element of her economic vision, including the moribund U.S.-EU trade pact, the Trans-Atlantic Trade and Investment Partnership. “I’m not happy that the trans-Pacific accord now probably won’t become a reality,” she said. “I don’t know who will profit from that. I’ll restrain my predictions for now.” Merkel, whose 11 years in power make her the longest-serving leader among the world’s top economic powers, cited the pitfalls that have emerged with the rise of populist movements. They include the anti-immigration Alternative for Germany party that’s draining votes from her Christian Democratic Union. Pushing back will require legal measures against hate speech, Merkel said. “Opinion formation proceeds differently now than it did 25 years ago,” she said. “We have to learn to deal with that.” ‘Grotesque’ Expectations European establishment politics has been buffeted by populist movements, highlighted by the U.K. vote in June to exit the European Union. Looming tests for governments include an Italian referendum next month and national elections next year in France, the Netherlands and Germany. Those shifts and the needs of Germany’s export-driven economy are increasing pressure on Merkel to step up as the bulwark of the western establishment, a role she signaled she’s resisting. Merkel called such an elevated role “grotesque and absurd” as she announced her re-election bid. “No person alone, even with the greatest experience, can fix the situation for better or worse in Germany, Europe and the world – and certainly not a German chancellor,” she said.
