Due to the clash in the Upper House over the contentious state secrets bill, Prime Minister Shinzo Abe's government will not pursue approval in the current Diet session of two deals signed earlier this year to export nuclear reactor technology and know-how to Turkey and the United Arab Emirates.

In May, Japan and Turkey signed a $22 billion deal with a Japanese-French consortium to build a nuclear power plant in Sinop, on the Black Sea coast. The consortium includes Mitsubishi Heavy Industries Ltd. and Itochu Corp. Construction of four reactors is slated to begin in 2017, and the first reactor is scheduled to begin operating from 2023.

Also in May, Japan and the UAE signed a nuclear cooperation agreement, paving the way for future exports of nuclear technology to oil- and gas-rich Abu Dhabi, which seeks to eventually have nuclear power provide up to 25 percent of its electricity.
