Asia-Pacific markets are set to open lower Monday, as investors assessed threats from the Trump administration toward Greenland over the weekend and looked toward key economic data from China.

Over the weekend, U.S. President Donald Trump and European leaders exchanged tense rhetoric over the Arctic territory, with Trump threatening tariffs on eight European countries and demanding control of Greenland, which is part of Denmark.

European leaders responded by calling the threats “completely wrong” and “unacceptable.”

Over in Asia, China will release its fourth-quarter GDP numbers, along with December figures for retail sales, urban investment and industrial output.

Hong Kong Hang Seng index futures were at 26,640, lower than the HSI’s last close of 26,844.96.
