1. China strikes back: Beijing says that tariffs on about $3 billion worth of US imports are going into effect Monday, hitting 128 products ranging from pork to steel pipes.
The sanctions include tariffs of 15% on 120 American products -- such as fruits, nuts, wine and steel pipes -- and 25% on eight other products, including pork and recycled aluminum.
First proposed 10 days ago, the penalties are a response to President Donald Trump's tariffs on imports of steel and aluminum from China and some other countries.
Experts fear that tit-for-tat retaliatory measures could turn into a trade war.

4. Bahrain's big find: Bahrain has discovered its biggest oil field since 1932, according to the kingdom's official news agency.
The agency said the new oil field is forecast to contain "highly significant quantities" of oil and gas. It said the find it "understood to dwarf Bahrain's current reserves," but did not give details on volume.
Bahrain is not a member of OPEC, but it has signed an agreement with the cartel and other major producers to curtail output. That deal, which runs until the end of 2018, is designed to rid markets of excess oil and support prices.

The Institute for Supply Management will release its US manufacturing report for March at 10 a.m. ET.
An official government index that tracks manufacturing activity in China jumped in March. But a second index produced by Chinese media group Caixin, which places more weigh on smaller firms, declined.
