Japan and the United States wrapped up two days of talks on automobile trade Thursday and agreed that China should step up efforts to prevent the imitation of foreign auto parts.

The two countries focused on multilateral auto issues on the second day, following the first day's session on bilateral issues, Japanese officials said.

They agreed that China needs to increase efforts to protect intellectual property rights, including those for foreign auto parts, the officials said.

There was no discussion on specific measures to encourage China to protect intellectual property rights, because officials feel it is necessary to take unified action with other industries on the issue, Japanese officials said.
