Scott Henry, a farmer from central Iowa, expects a 15% decline in income this year because of tariff disruptions; bad climate conditions are also impacting his business.
Many of them, from farm states, were also planning to relay messages from their constituents about how they would prefer markets be reopened than rely on additional government aid, as the White House had recently suggested with an offer of $12 billion for farmers affected by tariffs.
"We have a good personal relation", Juncker said after the White House meeting with the president. He added that, "Tariffs are taxes". Rand Paul added on Twitter. 'If tariffs punish farmers, the answer is not welfare for farmers - the answer is remove the tariffs'.
Danielson says without a long term solution, farmers are not the only ones who will be impacted by the trade war.
"We're opening up markets". 'This is what we feared all along: that this would just turn into more aid programs'.
Trump has also accused Beijing of manipulating its yuan currency to give its exporters an edge, a charge rejected by China.
EU Trade Commissioner Cecilia Malmstrom, who will accompany Mr Juncker, expressed hope for a "de-escalation" of the tensions, but said the EU is drawing up a list of more U.S. products that could be hit with retaliatory duties if the trip fails.
Later this week, Trump will visit Iowa and IL, two other farm-belt states, as he seeks to shore up support for Republican candidates in those regions.
When the Trump administration imposed tariffs on $50 billion in Chinese imports in mid-June, China retaliated by targeting Mr. Trump's political base in the Midwest, imposing its own tariffs on US goods including soybeans.
The president said he was fighting to get America a better deal after decades of being taken advantage of by trading partners.
"Both the U.S. and the European Union drop all Tariffs, Barriers and Subsidies!"
The move would be the first expansion of U.S. tariffs on Chinese goods since a similar tax was imposed on US$34 billion worth of goods on July 6. China has retaliated with duties on soybeans and pork, affecting Midwest farmers in a region of the country that supported the president in his 2016 campaign. "Great for global economy", he tweeted late on Wednesday.
Trump also said the EU made a commitment to buy more USA soybeans and natural gas, but a European official disputed that characterization.
The lawmakers were particularly pleased that the announcement had a focus on soybeans. Every market is an important one, particularly China, which imports one of every three rows of USA soybeans.
In exchange, Trump said he won access for USA soybean producers, and for American natural gas.
