The Kruskal-Wallis test can be used to test for a difference between two populations. It will produce the same outcome as the two-tail Wilcoxon rank sum test.

The Kruskal-Wallis test is a non-parametric test that can be used to test for differences between two or more populations. It compares the medians of the populations, using a rank-based approach. The two-tail Wilcoxon rank sum test is also a non-parametric test that can be used to test for differences between two populations, based on their ranks. The Kruskal-Wallis test and the Wilcoxon rank sum test will produce the same outcome if used to compare only two populations. Therefore, the statement is true.
