When did the Norse and Thule Inuit peoples begin interacting in Greenland?

The Norse and the Thule Inuit peoples began interacting in Greenland sometime during the 13th century.12

While the Thule culture appeared in northern Greenland around 1100, and Norse settlers established colonies on the island beginning in 986, there is no evidence of contact between the two groups prior to the 1200s. Archaeological findings from the subsequent Inugsuk culture, which developed from the Thule culture in the 12th and 13th centuries, indicate that the Inuit eventually acquired Norse trade goods, such as woven wool cloth and church-bell metal, suggesting ongoing interaction between the populations.1324
