Could (Directly Or Indirectly) Cuba Be On Putin/Trump Summit Agenda In Helsinki?

On 16 July 2018, The Honorable Donald Trump, President of the United States of America, and H.E. Vladimir Putin, President of the Russian Federation, are scheduled to meet in Helsinki, Finland.  
 
The official schedule includes a one-on-one meeting, an expanded meeting with staff, and a luncheon.
 
What might be on the agendas?  Acceptance of territorial integrity.  Acceptance of territorial realities.  Exchange of interests.   Acceptance of political realities.  Acceptance of ideologies.  Retaining balance.  Acceptance of muscularity.  Strength by conflict.
 
Notable that neither head of state believes the meeting requires a moment, an announcement, an agreement, and accomplishment other than the optic of the meeting.  
 
For each president, a (or perhaps the) primary goal is to establish the mechanism for a visit to Washington DC by President Putin and to Moscow by President Trump.

If the Republic of Cuba is discussed, the topics may include the activities in the country by: China (infrastructure, telecommunications, durables, consumables, consumer products, military cooperation); Russia (infrastructure, power generation, railroads, military cooperation); Turkey (civil aviation, ports); and Venezuela (energy, financial services).  The Trump Administration would seek assistance from the Putin Administration towards fostering commercial, economic and political changes in the Republic of Cuba.  There would likely none to minimum assistance.
