President Donald Trump has spent the last week railing against trade policies that allegedly put the U.S. companies at a disadvantage.Though economists, fact-checkers and even members of Trumpís own party have called the presidentís international trade analysis into question, inventor and Tesla chief executive Elon Musk appears to agree (in part) with Trump.Musk, 46, was a member of Trumpís advisory council before stepping down following the presidentís decision in June to pull the United States out of the Paris climate agreement.Amid a series of tweets Thursday, Musk - apparently frustrated by the Asian nationís import duties - compared Chinaís trade policy to "competing in an Olympic race wearing lead shoes."Musk made his argument after responding to a Trump tweet demanding that China reduce its trade deficit with the United States.Read More: Trump says Florida lawmakers were Ďlistening to meí on arming school personnel"Do you think the US & China should have equal & fair rules for cars?," Musk tweeted. "Meaning, same import duties, ownership constraints & other factors."Musk continued to lay out his frustration with the current trade relationship, pointing out a significant disparity in the import duties each country places on the other nationís cars.He tweeted, "For example, an American car going to China pays 25% import duty, but a Chinese car coming to the US only pays 2.5%, a tenfold difference" and "I am against import duties in general, but the current rules make things very difficult. Itís like competing in an Olympic race wearing lead shoes."Do you think the US & China should have equal & fair rules for cars? Meaning, same import duties, ownership constraints & other factors.— Elon Musk (@elonmusk) March 8, 2018Musk also noted that, U.S. auto companies in China are barred from owning "even 50% of their own factory," while there are five "100 percent China-owned EV auto companies in the U.S."Musk finished his tweets by pointing out that heíd raised his concerns with the Obama administration, but "nothing happened"."Hope this does not seem unreasonable," he tweeted in conclusion.Trump did not immediately respond to Muskís flurry of tweets.Talk of tariffs on aluminum and steel has captivated conversation in the nationís capital ever since Trump tweeted that "trade wars are good, and easy to win" earlier this month. The president said he would introduce tariffs of 25 percent on imported steel and 10 percent on aluminum, figures that sent minor shock-waves through the stock market.Though automakers like General Motors say the vast majority of the steel they use is domestic in origin, experts warn that tariffs will increase the price of steel and auto parts, as well as the price of cars.On Thursday, Trump said he intended to impose tariffs on imported steel and aluminum, but may exempt imports from Canada. The ultimate decision, he said, will hinge upon negotiations with the North American Free Trade Agreement.
