EU chief Ursula von der Leyen said the bloc was ready to take all "necessary" steps to safeguard its economic interests, after US President Donald Trump announced that he would impose 30% tariffs on all EU goods.

President Donald Trump on Saturday announced 30 percent tariffs on all European goods entering the U.S., prompting pushback from European allies.

"In a non-deal scenario without another delay of US tariffs, I see the EU going for a tit-for-tat approach, ie imposing 30% tariffs on selected US goods, not yet all goods, like the well-known motorcycles, cars, clothing and alcohol," he said in emailed comments.

The EU plans to impose 30% tariffs on €100 billion of U.S. goods as retaliation if no trade deal is reached by Aug. 1, heightening uncertainty.

Italy's foreign minister warned that, while he hopes for successful negotiations, the EU will respond resolutely to Trump's latest tariff threat.

"Other trading partners observing these threats will have the same mistrust of the negotiation process," experts argue.

Unlike the European Union, the Japanese government has made no indication it plans to impose any kind of reciprocal tariff on the U.S.

The European Union has finalized a second list of countermeasures to target U.S. goods worth $84 billion, including Boeing Co. aircraft, automobiles and bourbon, if it decides to retaliate against Donald Trump's tariff policy.

The European Union braced on Friday for a possible letter from U.S. President Donald Trump outlining planned duties on the United States' largest trade and investment partner after a broadening of his tariff war in recent days.

The European Union has returned U.S. spirits to its proposed list of retaliatory tariffs. Here's what that could mean for Kentucky's bourbon industry.

President Donald Trump urged European leaders to follow his model of shutting down the borders to deal with immigrants who are 'killing' the country
