American manufacturers and members of the US Congress might shout the loudest when it comes to what they perceive to be unfair Chinese trade practices, but their concerns are shared by many in China's biggest trading partner, the EU.
Karel De Gucht, the European commissioner for trade, brought with him to China a list of frustrations as long as his arm as he tries to improve European companies' access to the world's second-largest economy.
While European-designed cars might dominate China's highways, and bilateral EU-China trade may have grown by almost a quarter to €395 billion (Dh2.03 trillion) last year, the EU, which is China's biggest export market, remains unhappy over intellectual property infringement, lack of market access, investment caps and bias in public procurement, to name but a few of the key issues.
The EU Chamber of Commerce in China recently painted a downbeat picture of the situation for European companies in China. Writing in state media, the chamber said executives at more than 40 per cent of European companies believed the regulatory environment had worsened for foreign firms over the past two years.
According to the EU, 70 per cent of European companies operating in China have suffered breaches of their intellectual property rights.
Countless foreign companies have found to their cost in recent decades that gaining access to China's 1.3 billion consumers is harder than they thought, with the country a series of diverse markets with different preferences.
Mr De Gucht is hoping his visit will at least ease some of the biases and regulatory burdens that make accessing the Chinese economy even more difficult.
But the grievances are not all on one side.
While Chinese companies have shown themselves increasingly keen to invest in Western European companies, they have sometimes been frustrated by national security considerations, even if this is less often a problem in Europe than in the US, and worries in the West that they are primarily making acquisitions to plunder the technology of European companies.
