The European Union said it had stepped up retaliation against the United States over illegal support to American companies by increasing the number of products subjected to additional duties.
The European Union, Canada, Japan and others accuse Washington of not fully complying with a World Trade Organization (WTO) ruling to end outlawed payments to US companies, a program known as the Byrd amendment.
The US House of Representatives last year approved a budget bill to scrap the measure in October 2007. But some funds can still be paid under the program for years after that, prompting protests from trading partners.
In a statement, the EU said the additional tariffs of 15% would be extended from May 1 to 32 new products ranging from paper products, textiles, pens and mobile homes.
They would take the total value of duties to $81.19 million in the 12 months from May 1, up from $36.9 million in the previous 12-month period, it said. (Reuters)
