An attempt is made at reformulating pion-nucleon interactions in such a form that the large annihilation cross section of antiproton or the recent experiments at Stanford could be understood better. For this purpose, a new space (K-space) is introduced. In terms of Kspace, charge conjugation can be expressed as a rotation through pi around its second axis multiplied by a rotation through pi around the second axis in the usual isotopic space. It is shown that if pion-nucleon interaction is assumed as invariant under rotations in Kspace (it is already invariant under rotations in the usual isotopic space if we assume charge independence), it can not be local, especially the part responsible for the creation and the annihilation of nucleon pairs. Possibilities of checking this assumption experimentally are discussed, and among these the amihilation of antinucleon by nucleon is discussed in some detail. (auth)
