Kingdom, where during the reign of King Narai they also acquired a Portuguese influence and were eventually reintroduced back into Cambodia as the Siamese armies attacked into Cambodia. New Zealand Cambodian chef Kethana Dunnet has even dubbed Cambodian cuisine "the original Thai cuisine". In the 17th century, the Portuguese and Spanish began introducing various new food crops, such as tomatoes, papaya, pineapple, corn, potato, sweet potato, cassava and chilli from the Americas that were incorporated into local dishes, while the French introduced pâté, salads, wine, coffee, asparagus and baguettes. After the Vietnamese annexation of Cambodia in 1834 and during the period of Vietnamese-controlled People's Republic of Kampuchea from 1979 to 1989 Khmer cuisine was subjected to Vietnamization, adopting dishes such as beef lok lak. In the decades after World War II, many Cambodian urban middle-class and elite families employed cooks trained to prepare French dishes, and the children of these households often did not learn cooking themselves. The transmission of Cambodian traditional culinary knowledge was even more disrupted by the subsequent war, starvation and refugee crisis in the 1970s and 1980s. In 1975 when the Khmer Rouge gained power the rice production in Cambodia had dropped by 84% in comparison with 1970, and the policies of the Khmer Rouge (such as the ban of private cultivation of food crops, ban of foraging, ban of private ownership of foodstuff, ban of private cooking and ban of private eating combined with the unattainable rice production quotas, forced labour and insufficient food rations) resulted in one of the deadliest famines in modern history, during which from 1975 to 1979 an estimated 500,000 to 1.5 million Cambodians perished (10–20% of the country's population). Nowadays, more and more Asian fast food chains (such as The Pizza Company, Lotteria, Pepper Lunch, Yoshinoya and Bonchon) and Western fast food chains (such as Burger King, KFC, Krispy Kreme and Carl's Jr.) are entering the Cambodian market, especially in Phnom Penh, and fast food is becoming increasingly integrated into the Cambodian food scene, particularly among the younger generation. In 2004 Malis, the first Cambodian fine dining restaurant in Phnom Penh, was opened. Since the early 2010s there has been an emerging grassroots culinary movement in Siem Reap termed "New Cambodian Cuisine" loosely consisting of six Cambodian chefs and restaurateurs (Pola Siv, Sothea Seng, Pol Kimsan and Sok Kimsan, Mengly Mork and Pheak Tim) experimenting with and modernizing traditional Cambodian
