Brief Explanations:

After gaining independence, Vietnam came under Communist - led government control. Cambodia also had a period under the Khmer Rouge regime which was a brutal regime. While both faced challenges, the description of brutal regime control is most fitting for the immediate post - independence period for both. Vietnam has made significant economic progress in recent decades and is not accurately described as remaining poverty - stricken. And neither achieved immediate global economic success right after independence.
