not directed against any specific country, Moscow saw it as placing Tokyo with Washington and Beijing firmly in the anti-Soviet camp. Officially, both sides continued to express the desire for better relations, but Soviet actions served only to alarm and alienate the Japanese side. The 1980s Soviet military buildup in the Pacific was a case in point. The 1980s saw a decided hardening in Japanese attitudes toward the Soviet Union. Japan was pressed by the United States to do more to check the expansion of Soviet power in the developing world following the December 1979 Soviet invasion of Afghanistan. It responded by cutting off contacts beneficial to the Soviet regime and providing assistance to "front line" states, such as Pakistan and Thailand. Under Prime Minister Yasuhiro Nakasone, Japan worked hard to demonstrate a close identity of views with the Reagan administration on the "Soviet threat". Japan steadily built up its military forces, welcomed increases in United States forces in Japan and the western Pacific, and pledged close cooperation to deal with the danger posed by Soviet power. This economic cooperation was interrupted by Japan's decision in 1980 to participate in sanctions against the Soviet Union for its invasion of Afghanistan and by its actions to hold in abeyance a number of projects being negotiated, to ban the export of some high-technology items, and to suspend Siberian development loans. Subsequently, Japanese interest in economic cooperation with the Soviet Union waned as Tokyo found alternative suppliers and remained uncertain about the economic viability and political stability of the Soviet Union under Gorbachev. Japan-Soviet trade in 1988 was valued at nearly US$6 billion. Although public and media opinion remained skeptical of the danger to Japan posed by Soviet forces in Asia, there was strong opposition in Japan to Moscow's refusal to accede to Japan's claims to the Northern Territories, known to the Japanese as Etorofu and Kunashiri, at the southern end of the Kuril Island chain, and the smaller island of Shikotan and the Habomai Islands, northeast of Hokkaidō, which were seized by the Soviets in the last days of World War II. The stationing of Soviet military forces on the islands gave tangible proof of the Soviet threat, and provocative maneuvers by Soviet air and naval forces in Japanese-claimed territory served to reinforce Japanese official policy of close identification with a firm United States-backed posture against Soviet power. In 1979, the Japanese
