Based on the prime graph of a finite simple group, its order is the product of its order components (see [4]). We prove that the simple groups PSU3(q) are uniquely determined by their order components. Our result immediately implies that the Thompson's conjecture and the Wujie Shi's conjecture [16] are valid for these groups.
