Chinese Premier Zhu Rongji and South Korean President Kim Dae Jung agreed at talks Wednesday to exchange port calls of their countries' naval ships, Chinese Foreign Ministry spokesman Sun Yuxi said.

The agreement was reached at talks at the Blue House presidential office in Seoul, Sun told reporters.

"The Chinese side agreed to accept the South Korean proposal that Chinese and South Korean military vessels exchange port calls," Sun said.

Sun added the agreement is another sign South Korean-Chinese cooperative ties are expanding into all sectors, including the military sector, from trade and economic exchanges.
