US congress raises taxes...

...on China. Indeed, the Senate is about to impose tariffs on the goods imported from China (i.e. a tax on Chinese produce sold in the US.)

The economists typically oppose such restrictions on the free trade, since such restrictions result in domestic consumer having to pay higher prices. The question is however complicated, with many strong arguments for protectionism, nicely summarized in Chapter 9 of Greg Mankiw's economics textbook. The argument used here is "The jobs argument", as well as "The infant industry argument", as some of the economists pointed out that "losing manufacturing meant losing our [US] edge in innovation."

The preservation of the manufacturing has been a hot topic lately, due to the apparently quick surge from the recession by the countries with a strong manufacturing base, most notably Germany.

The emphasis on manufacturing explains why the higher tariffs have bi-partisan support: while it is usually the Democrats who favor higher taxes and oppose free trade/free market, it is the Republicans who are most concerned about the manufacturing and the workers employed in the private industry.
