ok

Explanation:

Step1: Define subset symbol

The symbol $\subseteq$ means every element of the first set must be an element of the second set.

Step2: Identify elements of each set

Let $A = \{\text{Thailand}\}$, so its only element is $\text{Thailand}$. Let $B = \{\text{Thailand, Cambodia, Vietnam, Laos}\}$.

Step3: Verify subset condition

The element $\text{Thailand}$ from set $A$ is an element of set $B$. All elements of $A$ are in $B$.

Answer:

The statement $\{\text{Thailand}\}\subseteq\{\text{Thailand, Cambodia, Vietnam, Laos}\}$ is true.
