Russia has energy resources aplenty.
China lacks energy resources...and hungers for more.
Thus..it is only natural for President Putin to build bridges with China...figuratively...and literally with a record new span in the far east's...Vladivostok.
Putin is visiting China for 3 days...to conclude a nat gas deal that has been cooking for years.
And Putin hopes for more energy and business deals...as a buffer against the West and the EU.
