'The Gem Pearl of Bee'), also spelled as Tbong Khmum, is a province of Cambodia located on the central lowlands of the Mekong River.

It borders the provinces of Kampong Cham to the west, Kratié to the north, Prey Veng to the south and shares an international border with Vietnam to the east.

Tboung Khmum Province was formed when Kampong Cham Province was split in two by a royal decree signed on 31 December 2013 by King Norodom Sihamoni on the recommendation of Prime Minister Hun Sen.

[4] The CPP won only eight of the available 18 National Assembly seats in Hun Sen's home province.

The 10 districts that remain in Kampong Cham overwhelmingly voted for the opposition Cambodia National Rescue Party, led by Sam Rainsy, while five of the six districts cut out from Kampong Cham to form the Tboung Khmum Province were won solidly by the CPP.
