Lighthizer is due to meet Monday in Brussels with EU Trade Commissioner Cecilia Malmstrom to resolve the dispute ignited when Trump imposed steep duties on all steel and aluminum imports. Such a step would significantly escalate his trade war with Beijing and would likely increase costs for a broad range of US businesses and consumers.
That would cover virtually all the goods imported from the world's second largest economy.
"We will evaluate the comments and we will make a decision", Kudlow said, suggesting it could be some time before the fresh import charges will be levied.
China has said it's ready to impose retaliatory tariffs on $60 billion of US goods.
"That totally changes the equation", Mr Trump said.
Trump's threatened tariffs, now totalling $US517 billion in Chinese goods, would exceed the $US505 billion in goods imported from China previous year.
WASHINGTON-President Donald Trump threatened Friday to slap tariffs on all of the Chinese goods imported into the United States, ramping up the already tense trade relations with Beijing amid ongoing talks with Canada and the EU.
"Apple prices may increase because of the massive Tariffs we may be imposing on China - but there is an easy solution where there would be ZERO tax, and indeed a tax incentive", Trump tweeted. To a certain extent it's going to be up to China. Among the equipment hit were a number of components and devices used by U.S. tech firms, including chips and networking gear produced in Chinese factories. "The trade wars only serve as a catalyst for the turning of the cycle".
In a letter to U.S. officials as part of the public consultation on the measures, the company said some of Apple's Beats headphones and its new HomePod smart speaker would also face levies. "But I will say this: the world trading system is broken".
Trump said on Air Force One that he was ready to launch tariffs on 200 billion dollars worth of imports in the coming days.
The new duties will start to hit consumer products directly, including furniture, lighting products, tires, bicycles and auto seats for babies.
"Our concern with these tariffs is that the United States will be hardest hit, and that will result in lower USA growth and competitiveness and higher prices for U.S. consumers", Apple said in the letter.
