WASHINGTON — The Trump administration, confident that the Chinese government will follow through on its agreement to buy more American agriculture, plans to shutter its bailout program for farmers hurt by tariffs.

But allegations of unfairness and other criticisms continue to dog the $28 billion initiative, which President Trump created to ease the economic hardship on rural America, which constitutes a large portion of his political base.

What was meant to be a financial lifeline for struggling farmers has been widely derided by critics as a corporate bailout for big agriculture companies and those who live in metropolitan areas but own farms in rural America. The program has also been attacked for providing financial support to American subsidiaries of foreign agriculture companies that operate in the United States.

For months, a bipartisan group of lawmakers has been pressing the Trump administration to explain payments to a Brazilian-owned company with a troubled past.
