NUUK, Greenland (AP) — Greenland’s legislature debated Tuesday whether to prohibit political parties from receiving contributions “from foreign or anonymous contributors” after President Donald Trump laid out ambitions for the United States to take over the vast island that belongs to Denmark.

The law, billed as an effort “to safeguard Greenland’s political integrity,” came ahead of parliamentary elections.

Greenland plans to ban foreign and anonymous donations to its political parties after the Trump administration has said the US president is serious about taking control of the vast Arctic island. The government of Greenland on Monday put forward an emergency parliamentary proposal to safeguard the country’s “political integrity” ahead of elections due by April 6.

Mette Frederiksen, the country’s prime minister, hints at concessions but still insists landmass is not for sale

Greenland is a self-ruling territory in the Danish kingdom, which means policymakers in Nuuk control most domestic issues. Denmark, which oversees defense and security policy on the mineral-rich Arctic island, is injecting 14.6 billion kroner ($2 billion) to ramp up defenses.
