US threatens action for sanction violations putting emphasis on Iran

The United States will take all alleged sanctions violations seriously and will take appropriate action, a State Department spokesman said on Friday, responding to a question about a tanker unloading Iranian fuel oil at a Chinese port.

Reuters on Thursday reported that a tanker carrying Iranian fuel oil had unloaded the cargo into storage tanks near the Chinese city of Zhoushan.

"We are committed to enforcing our sanctions, especially those related to Iran's oil and petrochemicals sectors," the spokesman said but declined to comment on the specific report.
