U.S. President Barack Obama expressed full support Tuesday for Seoul's response to the March sinking of a South Korean naval ship in his telephone conversation with South Korean President Lee Myung-bak, Lee's office in Seoul said.
"President Obama emphasized that the U.S. fully trusts and supports South Korea's response and investigation by an international team," Cheong Wa Dae said.
In Washington, a White House statement said the two leaders "emphasized the importance of obtaining a full accounting of the event and committed to follow the facts of the investigation wherever they lead."
It also said U.S. Secretary of State Hillary Clinton will visit South Korea next week to discuss the ship sinking.
The phone call comes ahead of an announcement Thursday on the results of a weeks-long investigation on the sinking of South Korean patrol ship Cheonan.
