WASHINGTON - President Donald Trump said Friday he could move "very soon" to impose tariffs on an additional $200 billion in imports from China, threatening to escalate a trade fight with the world's second-largest economy.

Mr. Trump told reporters on Air Force One that his plans to slaps taxes of up to 25 percent on Chinese imports would depend on the choices made by that country's leaders.

"To a certain extent it's going to be up to China," he said.

Mr. Trump claims that China's trade policies are unfair, including the widespread practice of requiring foreign companies operating there to share intellectual property. He has pointed to the large U.S. trade deficit -- the gap between U.S. imports and exports -- with the People's Republic as a sign of that imbalance.

"Trump's threat shows that he remains fully invested in a maximum pressure campaign against Beijing," Eurasia Group analysts said in a report. "Many in the White House, including Trump, believe that Washington's tariffs have hurt the Chinese economy and will make Chinese leaders desperate enough to address the structural concerns at the heart of the dispute. Trump's comments today push that strategy even further."

The U.S. trade deficit widened for the second straight month in July, reaching the highest level since February, as imports hit an all-time high. The deficit in goods with China and the European Union set records.

The tariffs would potentially hurt U.S. companies that import everything from handbags to bicycle tires. A public comment period on the import taxes ended Thursday. China has said it's ready to impose retaliatory tariffs on $60 billion of U.S. goods.

"We expect the administration to make an announcement in the coming days that it has decided to impose the tariffs, though we do not expect them to go into effect until October at the earliest, and they are likely to be implemented incrementally," Barclays analyst Michael Gapen said in a research note.

The U.S. has already imposed tariffs on $50 billion in Chinese imports, and Beijing punched back with an equal amount.

Levies imposed by China to hit back against that earlier round of tariffs has affected American farmers, who export soybeans, sorghum and other crops to the country. Other retaliatory tariffs have hit consumer products from seafood to wedding tents and cases for firearms.

The Trump administration in July announced a $12 billion emergency aid package to help farmers affected by tariffs.

Mr. Trump also said on Friday that trade talks with Canada are "moving along." The negotiations are part of the administration's efforts to revise the North American Free Trade Agreement. Talks between U.S. and Canadian trade officials broke off last week without a deal.

Although experts say heightened U.S. protectionism is likely to have a relatively modest impact on the broader economy, consumers could feel the pinch.

"Losses to consumers, who end up paying higher prices for many goods, are likely to be several times larger than net economic costs to the economy as a whole," Gapen wrote.
