Abstract: Let $k$ be a function field in one variable over $\mathbb C$ or the field $\mathbb C((t))$. Let $X$ be a $k$-rationally simply connected variety defined over $k$. In this paper we show that $R$-equivalence on rational points of $X$ is trivial and that the Chow group of zero-cycles of degree zero $A_0(X)$ is zero. In particular, this holds for a smooth complete intersection of $r$ hypersurfaces in $\mathbb P^n_k$ of respective degrees $d_1,\ldots ,d_r$ with $\sum \limits _{i=1}^{r}d_i^2\leq n+1$.
