BEIJING, April 20 (Xinhua) -- Chinese foreign ministry spokesperson Guo Jiakun on Monday expressed concern over the U.S. interception of a vessel, after media reports said the United States had seized an Iranian cargo ship heading toward an Iranian port.

The situation in the Strait of Hormuz is sensitive and complex, Guo said at a regular news briefing.

China hopes that relevant parties will abide by the ceasefire agreement with a responsible attitude, avoid escalating conflicts and intensifying tensions, and provide the necessary conditions for the restoration of normal passage through the strait, Guo said. ■
