President Trump's trade plans are likely to be significantly clearer by the end of this week, but an array of comments from the president and his team have underlined to markets that finality may be elusive.

President Trump said the U.S. will impose steep levies on imports from 20 countries starting next month, raising pressure on trading partners.

American tariffs on dozens of countries will come into effect next Wednesday as scheduled, although several deals could still be worked out before then, President Donald Trump confirmed Friday.
