GMU lawprof Eugene Kontorovich writes about this:

The divestment action manifests a singular animosity towards Israel. The Presbyterians have not divested their funds from any of the cruel regimes of the world: not from China for its ethnic cleansing of Tibetans, and its repression of Muslems and Falun Gong; and not even from Sudan, currently engaged in the extermination of Africans in Darfur. But then again, Syria has not boycotted those states either.

One would expect the Presbyterian Church to use its economic clout with an eye to punishing the many regimes around the world that oppress their fellow Christians, and call attention to their plight. However, the church has not taken action against such nations as Sudan, Somalia, Nigeria, or North Korea (whose government has reportedly murdered 300,000 Christians), where anti-Christian persecution has been detailed by Christian human-rights groups. . . .

Some readers pointed this out, and Eugene Kontorovich (the author of the op-ed I linked to on the subject) also confirms it: The divestment action was taken, as the op-ed mentioned, by the Presbyterian Church (U.S.A.); but there are other Presbyterian denominations in America that didn't join in that. No word on what the Judean People's Liberation Front has to say about that.
