Reuters Poll: China unperturbed by trade war at the street level

Campaign launched in Senegal to support Turkish brands

China lodged its challenge at the WTO on Tuesday, the statement said.

The duties also apply to imports of solar cells and modules from Europe, Canada, Mexico and South Korea.

But many have speculated that the affects could cause significant harm to US industries.

Of course, tariffs have been a mainstay in Canadian headlines for the past several months, with Trump levying duties on US imports of Canadian steel and aluminum.

On the other hand, China recently asked the United States to treat investors of the Asian giant objectively and precisely with regard to the recently signed the Foreign Investment Risk Review Modernization Act. This led to complaints that it undermined the World Trade Organization. USA officials say such action is necessary because the WTO lacks the ability to address Chinese trade tactics.

China has tried to portray itself as a defender of the WTO's trade system. "Other Countries should not be allowed to come in and steal the wealth of our great United States of America".

The European Union filed its own WTO complaint in June against Chinese technology policies that it said violate Beijing's free-trade commitments.

WTO complaints begin with negotiations between the parties to the conflict. If those fail, the case moves to a panel of experts who can decide whether the trade controls are improper.

The new round of tariffs marked the completion of Trump's threat to impose $50 billion of import taxes on Chinese goods, the first $34 billion of which went into effect on July 6.

China responded two days later by proposing tariffs ranging from 5 percent to 25 percent on 5,207 USA goods worth 60 billion dollars. "We urge the USA side to take practical action, respect WTO rules and abandon its wrong practices, to bring the trade of related products back to normal". Beijing says it will retaliate.

On May 31, Canada announced it would impose "dollar-for-dollar" tariffs on 16.6 billion Canadian dollars (12.7 billion dollars) worth of US imports on July 1 if Washington does not drop its steel and aluminum tariff threat.

Since the start of the year, the United States has been wielding tariffs against its trading partners worldwide to alter what President Donald Trump calls "unfair trade practices".

Below is a review of the global trade spat so far this year.

Beyond tariffs, currency concerns have re-emerged as an issue in the Trump administration, and they are expected to come up during this round of talks. "There are not yet any trade deals". So far, the Trump administration has declined to give China the label, saying that while China manipulated its currency in the past, that problem had dissipated for now.
