1. China's economy shows more signs of slowing. Retail sales in April grew at their slowest annual pace since May 2003 while industrial output and fixed asset investment also weakened.
2. The stock market could determine the outcome of the trade war.

3. Here's the list of $300 billion worth of Chinese goods that'll get hit if Trump raises tariffs.
