From Wall Street Journal:
China launched formal complaints at the World Trade Organization in a bid to take down trade barriers set up by the European Union and U.S., a sign Beijing is fighting more aggressively to keep foreign markets open for its exports.
The targets of its two complaints are high EU import tariffs on Chinese screws and a U.S. ban on the import of Chinese poultry. Beijing had already announced the suit against the U.S.
China insists it is countering protectionism and fears about job losses at home in a slumbering global economy. Brussels and Washington say the sanctions are justified by lax business and health rules in China. The EU and the U.S., the two biggest buyers of Chinese goods, combined for $610 billion of imports from China last year.
