The Netherlands is preparing for United States sanctions on the International Criminal Court (ICC) that could be announced as early as Monday, according to The Associated Press (AP), which spoke to diplomatic and government officials on condition of anonymity; The Wall Street Journal reported that Washington is preparing sweeping economic restrictions on the institution.

The measures would escalate the Trump administration’s campaign against the court, which has already hit more than a dozen officials, including half of its sitting judges, and which Secretary of State Marco Rubio described as a campaign to “dismantle the threat” posed by the tribunal. The Hague is looking at ways to keep paying staff and protecting witnesses, and has asked for a six-month grace period before the sanctions take effect. The measures are retaliation for the court’s investigations of US and Israeli officials, whose countries are not members of the court, and Venezuela and Chad have announced in recent months that they will leave the body.
