Electric potential and movement of charges

If electric field is not present does that mean that charges achieve condition of electrostatics I.e, charges are stationary ? But we say that stationary charge can produce electric field. I read this statement one a page (link given below) "Now if there's any $\vec E$ inside the conductor , we can surely say then the charges must move ."

If there is an electric field, then there will be a force on a charged particle since $\vec{F} = q \vec{E}$. If you put a single charged particle in perfect vacuum, then if you add another charged particle then both particles must either move away from or towards one another, depending on whether the charges of the two particles have the same or opposite sign.
