"The discovery of Indus seals manufactured with non-Indus raw materials, but with tools and techniques associated with Indus productions, further supports the idea that merchants and craftsmen from the greater Indus Valley were living and working at interior settlements in the Oman peninsula."

Recent work at Harappa by the Harappa Archaeological Research Project shows that a new study of artifacts recovered from the 1999 and 2000 seasons at the site has revealed the presence of silk.
