Shouldn't に be used here instead of へ? As far as I know, the function of へ is
to denote the direction in which an action is taken, not a direction in which
an action is taken.

question
grammar meaning particles
Is this usage of へ wrong?
に cannot be used because にの is an invalid combination. On the other hand, への
is valid and compatible with 設置(する) probably because 設置 indicates something of
direction ( _putting ... on **to**_ ).

Note 満洲{へ,で,に}研究施設が設置される are possible. Then nominalizing them requires の after
満州＋particle, so that they become 満洲{への，での}研究施設 **の** 設置.
