Kudlow, speaking at the Economic Club of New York, also said China's economic reforms were moving in the wrong direction and that he expected the United States would soon announce tariffs on an additional $200 billion worth of Chinese goods.
"We are ready to negotiate and talk with China any time that they are ready for serious and substantive negotiations toward free trade to reduce tariffs and non-tariff barriers, to open markets, to allow the most competitive economy in the world, ours, to export more and more goods and services to China," Kudlow said.
Administration officials said on Saturday that President Donald Trump was likely to announce the new tariffs on about $200 billion of Chinese imports as early as Monday.
The tariff level will probably be about 10 percent, the Wall Street Journal reported, quoting people familiar with the matter. That is below the 25 percent the administration said it was considering for this possible round of tariffs.
The upcoming tariffs will be on a list of items that included internet technology products and other electronics, printed circuit boards and consumer goods, including Chinese seafood, furniture and lighting products, tires, chemicals, plastics, bicycles and car seats for babies.
It was unclear if the administration will exempt any of the products that were on the list, which was announced in July.
