Article: An ancient Indian treatise on statecraft, economic policy and military strategy by Kautilya and Vishnugupta, who are traditionally identified with Chanakya (c. 350-283 BCE). In this treatise, the behaviors and relationships of the people, the King, the State, the Government Superintendents, Courtiers, Enemies, Invaders, and Corporations are analysed and documented. Roger Boesche describes the Arthasastra as "a book of political realism, a book analysing how the political world does work and not very often stating how it ought to work, a book that frequently discloses to a king what calculating and sometimes brutal measures he must carry out to preserve the state and the common good."

Article: However, the 18th century saw the European empires gradually expand across the world, as European states developed economies built on maritime trade. The dynasty was confronted with newly developing concepts of the international system and state to state relations. European trading posts expanded into territorial control in nearby India and on the islands that are now Indonesia. The Qing response, successful for a time, was in 1756 to establish the Canton System, which restricted maritime trade to that city and gave monopoly trading rights to private Chinese merchants. The British East India Company and the Dutch East India Company had long before been granted similar monopoly rights by their governments.

Question: Which two European companies traded in Canton?
Ans: British East India Company and the Dutch East India Company
