Israel has authorised the construction of 3,000 more housing units in occupied East Jerusalem and the West Bank, according to Israeli officials.
It is also speeding up the processing of 1,000 planning permissions.
The decision comes a day after a vote at the UN General Assembly upgraded the Palestinians' status at the UN to that of non-member observer state.
The US said the expansion plan was counterproductive and would make it harder to resume peace talks.
"We reiterate our longstanding opposition to settlements and East Jerusalem construction and announcements," White House spokesman Tommy Vietor said.
Earlier Palestinian President Mahmoud Abbas called for an end to settlement building and a return to peace talks.
According to the Israeli Haaretz newspaper, some of the new units will be between Jerusalem and the settlement of Maale Adumim.
Plans to build settlements in the area, known as E1, are strongly opposed by Palestinians, who say the development will cut the West Bank in two, preventing the creation of a contiguous Palestinian state.
I suppose we should thank the kind Israeli government for building all these homes for eventual use by Palestinian families when the illegal settlers have been sent back to the land of Israel they purport to love so much (but just don't want to live in).
