"40 Years’ Development of X’s Outward Foreign Direct Investment", is it correct?
X is a country name. I am thinking which title is correct:
1) 40 Years’ Development of X’s Outward Foreign Direct Investment
2) 40 Years Development of X’s Outward Foreign Direct Investment
3) 40-Year Development of X’s Outward Foreign Direct Investment
Let me know if you have other suggestions. Thanks!
