Perak is a state of Malaysia on the west coast of the Malay Peninsula. Perak has land borders with the Malaysian states of Kedah to the north, Penang to the northwest, Kelantan and Pahang to the east, and Selangor to the south. Thailand's Yala and Narathiwat provinces both lie to the northeast. Perak's capital city, Ipoh, was known historically for its tin-mining activities until the price of the metal dropped, severely affecting the state's economy. The royal capital remains Kuala Kangsar, where the palace of the Sultan of Perak is located. As of 2018, the state's population was 2,500,000. Perak has diverse tropical rainforests and an equatorial climate. The state's mountain ranges belong to the Titiwangsa Mountains, which is part of the larger Tenasserim Hills system that connects Myanmar, Thailand and Malaysia.

Pahang, officially Pahang Darul Makmur with the Arabic honorific Darul Makmur is a sultanate and a federal state of Malaysia. It is the third largest state in the country and the largest state in Peninsular Malaysia by area, and ninth largest by population. The state occupies the basin of the Pahang River, and a stretch of the east coast as far south as Endau. Geographically located in the East Coast region of the Peninsular Malaysia, the state shares borders with the Malaysian states of Kelantan and Terengganu to the north, Perak, Selangor and Negeri Sembilan to the west, Johor to the south, while South China Sea is to the east. The Titiwangsa mountain range that forms a natural divider between the peninsula's east and west coasts is spread along the north and south of the state, peaking at Mount Tahan, which is 2,187 metres (7,175 ft) high. Although two thirds of the state is covered by dense rain forest, its central plains are intersected by numerous rivers, and along the coast there is a 32-kilometre (20 mi) wide expanse of alluvial soil that includes the deltas and estuarine plains of the Kuantan, Pahang, Rompin, Endau, and Mersing rivers.
