In the late 1980s, the Japanese government was making a concerted effort to enhance its diplomatic stature, especially in Asia. Toshiki Kaifu's much publicized spring 1991 tour of five Southeast Asian nations—Malaysia, Brunei, Thailand, Singapore, and the Philippines—culminated in a 3 May major foreign policy address in Singapore, in which he called for a new partnership with the ASEAN and pledged that Japan would go beyond the purely economic sphere to seek an "appropriate role in the political sphere as a nation of peace." As evidence of this new role, Japan took an active part in promoting negotiations to resolve the Cambodian conflict.
