1. Trade war escalates: The Trump administration has announced a new round of tariffs on Chinese goods worth $200 billion that will go into effect next week.

President Donald Trump had urged his advisers to press forward with the tariffs, even as Washington and Beijing worked to restart trade talks.

Trump's decision threatens to upend the possibility of a diplomatic breakthrough with Chinese negotiators.

The United States will charge a 10% tariff on the imports, increasing to 25% at the end of the year. The additional tariffs are on top of penalties enacted earlier this year on $50 billion worth of Chinese goods. Taken together, it means roughly half of the products that China sells to the United States each year will be hit by American tariffs.

The Chinese government said it would retaliate.

2. Global market overview: Markets were calm despite another escalation in the trade war between the world's two biggest economies.

US stock futures were pointing up and European markets opened mostly higher.

Asian markets ended the session mixed.

"It seems as if the latest tariff announcement was largely priced in," said Hussein Sayed, chief market strategist at FXTM.

3. Google goes driving: Google (GOOGL) will integrate its Android operating system into cars produced by Renault, Nissan and Mitsubishi under a partnership announced Tuesday.
