"China does not demonstrate cowardice, but at the same time does not exert pressure on the USA amid trade frictions", Bian pointed out, stressing that Beijing has "a whole set of adequate countermeasures" to respond to Washington's tariff war.
Trump, meanwhile, broadened his trade tirades on Twitter into agriculture, writing: "Canada has all sorts of trade barriers on our Agricultural products".
The peso sank to its weakest in more than a year earlier Tuesday on concern the USA may leave the North America Free Trade Agreement and try to negotiate two separate free trade deals with Mexico and Canada.
Mexico will import more pork products from Europe after imposing a 20 percent tariff on US pork legs and shoulders in retaliation to steel tariffs, Economy Minister Ildefonso Guajardo said on Tuesday.
The announcement last week, and a coming list of proposed products, is just the latest in a long line of moves that Trump administration cabinet members including Wilbur Ross, economic advisor Larry Kudlow, and Treasury Secretary Steven Mnuchin have all suggested were leverage for negotiations.
"We need trade and one of the things we're concerned about is long-term implications that these trade issues will have on our partnerships with Mexico and Canada and other markets", said Iowa Secretary of Agriculture Mike Naig, a Republican.
Mexico will challenge the United States' metal tariffs at the World Trade Organization (WTO) on the grounds that they violate worldwide trade rules, the government said today.
Mexico said it would impose import duties on $3 billion worth of USA products, including cheese, bourbon, pork and others, making good on its threats that it would retailiate for US tariffs on steel and aluminum.
He said he hasn't talked to the federal government yet about the possibility of federal financial support for producers in Canada's metals sector.
The Koch's network of organizations - Americans for Prosperity, Freedom Partners Chamber of Commerce and the LIBRE Initiative - now say they will be spending the rest of 2018 and millions of dollars defending job-killing free trade deals and opposing Trump's tariffs on aluminum, steel, and Chinese products.
Canada, Mexico and the European Union had been enjoying a reprieve from the Trump administration's tariffs, but that ended Friday. "Companies are experiencing damages and interruptions today".
Conservative Leader Andrew Scheer pressed Trudeau on the issue during Question Period, asking why the government had delayed its retaliatory action. International Air Transport Association (IATA) director general Alexandre de Juniac said the tariffs are "bad news" that would harm the airline industry. China has vowed to retaliate on everything from US soybeans to airplanes, and Beijing has said it will abandon its commitments if the USA follows through on its tariff threat.
Trudeau replied he wants to follow through on the consultations while trying to persuade the U.S.to drop the tariffs. For example, Republican Senator Marco Rubio (one of Trump's competitors for the 2016 presidential nomination) tweeted, "Sadly #China is out-negotiating the administration & winning the trade talks right now".
