Claim: G20's summits have had people.
Evidence: The G20 heads of government or heads of state have periodically conferred at summits since their initial meeting in 2008 , and the group also hosts separate meetings of finance ministers and central bank governors.
The term `` head of government '' is often differentiated from the term `` head of state '' , -LRB- e.g. as in article 7 of the Vienna Convention on the Law of Treaties , article 1 of the Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons , including Diplomatic Agents and the United Nations protocol list -RRB- , as they may be separate positions , individuals , and/or roles depending on the country.
