The clause's objective is to facilitate the soft landing of post Soviet and Eastern Europe (e.g., Russia) into the GATT/WTO regime, and thus serves as a transitional measure. The energy materials and products are defined in ANNEX EM, and include items such as uranium ore, coal, coal gas, tar, petroleum, purified petroleum, natural gas, bitumen, asphalt, electrical energy, fire wood, and charcoal. これは、ロシを初めとした旧ソ連・東欧等のWTO非加盟が、GATT/WTO体制にソフトランディンできるようにする、いわばWTO加盟への準規定と言うことができよう。 - 経済産業省
