st: two-way cluster-robust covariance matrix estimates

Subject   st: two-way cluster-robust covariance matrix estimates

Dear all,
Please ignore my previous question from yesterday (titled: robust
clustered errors in panel data). I read both "Evaluating one-way and
two-way cluster-robust covariance matrix estimates" ( Baum, Nichols
and Schaffer) & "Clustered Errors in Stata"  (Nichols and Schaffer)
and gained much understanding.
Still I would appreciate if any of you can help me resolve one issue.
I have an unbalanced panel of macroeconomic data on 35 countries over
17 years. I want to run a FE model with clustered errors where the
cluster id=country code.
I tested for time-fixed effects and confirmed their existence.
My question is, does employing (xtivreg2, fe cluster (id year),
equivalent to running one way clustering  (xtreg, fe vce(cluster id))
including years dummies in the regression?
Any hint of what should guide me in choosing one option over the other?
I will really appreciate any advice
