"President Donald Trump, already embroiled in a trade battle with China, plans to ratchet commercial tensions higher by barring many Chinese companies from investing in U.S. technology firms, and by blocking additional technology exports to Beijing," The Wall Street Journal's Bob Davis reports.

Why it matters, from Chris Krueger of Cowen Washington Research Group: "Of all the strands of U.S. trade and sanctions policy against China, perhaps least appreciated by markets is the potential for significant investment restrictions and export controls to be recommended by Treasury by the end of [this] week, ... and implemented soon thereafter by President Trump. This opens a major new front in the U.S.-China conflict, adding fuel to the ongoing trade war with potentially wide-ranging effects on financing markets."
