This study examines the validity of long-run purchasing power parity (PPP) between China and a sample of 18 Latin American countries from January 2000 to December 2020. We adopt the nonparametric nonlinear rank tests for analysis without prior knowledge and specification of the functional form. We also address the rank problems that may occur in multivariate models. The rank tests indicate the absolutely strong evidence of an unrestricted PPP relationship with reasonably strong evidence of nonlinearity in the data. Our results justify a favorable prospect of closer economic cooperation between China and Latin American countries in the future.
