Agriculture minister Yoshiyuki Kamei voiced concern Friday over a joint proposal issued by the United States and the European Union on World Trade Organization farm trade talks, ministry officials said.
"There are areas where Japan has difficulty in responding," Kamei said during a meeting with Richard Christenson, deputy chief of mission at the U.S. Embassy.
The joint proposal includes the establishment of an upper limit for tariffs on farm products and the expansion of low-tariff import quotas on such products.
