grey substanceとは 意味・読み方・使い方

There were great many difficulties in the implementation of a safeguard measures system under Article XIX of GATT, including the fear that countries that were targets of safeguard measures would retaliate with their own restrictive measures. Since the 1970s, there had been a tendency to move to voluntary export restrictions ? so-called "grey-area measures" that have no clear basis in the GATT and, thus, raise concerns that the GATT system might become empty of meaning and substance.例文帳に追加
