BEIJING/BRUSSELS/PARIS (Reuters) - China announced additional tariffs of 34% on U.S. goods on Friday, the most serious escalation in a trade war with President Donald Trump that has fed fears of a recession and triggered a global stock market rout.

Beijing also announced it was adding several U.S. entities to an export control list and classifying others as an "unreliable" entity.

Nations from Canada to China have readied retaliation in an escalating trade war after Trump raised U.S. tariff barriers to their highest level in more than a century this week, leading to a plunge in world financial markets. 

In Japan, one of United States' top trading partners, Prime Minister Shigeru Ishiba said that the tariffs had created a "national crisis" as a plunge in banking shares on Friday set Tokyo's stock market on course for its worst week in years.

Investment bank JP Morgan said it now sees a 60% chance of the global economy entering recession by year end, up from 40% previously.
