Context paragraphs:
Immigration to Romania: Romania, though not a popular destination for immigrants, has recently experienced a growing wave of immigration, mostly from the Republic of Moldova, Turkey and China, but also from Africa, the Middle East, and the former Soviet Union.  In 2013, there were 198,839 immigrants living in Romania, of which 13,000 were refugees.  Over half of the country's foreign-born residents originate from Republic of Moldova.  Owing to the former period of union between most of Moldova and Romania, many Moldovans are eligible for Romanian citizenship on the basis of descent.  Immigration is expected to increase in the future, as large numbers of Romanian workers leave the country and are being replaced by foreigners.

ISO 3166-1 numeric: ISO 3166-1 numeric (or numeric-3) codes are three-digit country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest.  They are similar to the three-digit country codes developed and maintained by the United Nations Statistics Division, from which they originate in its UN M.49 standard.  They were first included as part of the ISO 3166 standard in its second edition in 1981, but they were released by the United Nations Statistics Division since as early as 1970.

Napa cabbage: Napa or nappa cabbage ("Brassica rapa" subsp.  "pekinensis" or "Brassica rapa" Pekinensis Group) is a type of Chinese cabbage originating near the Beijing region of China, and is widely used in East Asian cuisine.  Since the 20th Century it is also a widespread crop in Europe, America and Australia.  In much of the world, this is the vegetable referred to as "Chinese cabbage".

Foreign branding: Foreign branding is an advertising and marketing term describing the use of foreign or foreign-sounding brand names for companies, products, and services.  When the actual country of origin may not be beneficial, companies tend to use a foreign branding strategy, trying to make customers believe that the company and/or its products originate from a more favourable country than they actually do.

Regional cuisine: Regional cuisine is cuisine based upon national, state or local regions.  Regional cuisines may vary based upon food availability and trade, varying climates, cooking traditions and practices, and cultural differences.  One noteworthy definition is based upon "traditional cuisine": "A traditional cuisine is a coherent tradition of food preparation that rises from the daily lives and kitchens of a people over an extended period in a specific region of a country, or a specific country, and which, when localized, has notable distinctions from the cuisine of the country as a whole."  Regional food preparation traditions, customs and ingredients often combine to create dishes unique to a particular region.  Regional cuisines are often named after the geographic areas or regions that they originate from.

List of missiles by country: This list of missiles by country displays the names of missiles in order of the country where they originate (were developed), with the countries listed alphabetically and annotated with their continent (and defence alliance, if applicable).  In cases where multiple nations have developed or produced a missile, it is listed under each significantly participating nation.  Within the lists of each country, missiles are ordered by designation and/or calling name (the latter being especially relevant for Russian/Soviet missiles).  In some cases multiple listings are used, in order to provide cross-references for easier navigation.

Kkakdugi: Kkakdugi or diced radish kimchi is a variety of kimchi in Korean cuisine.  Usually, it has all the ingredients of kimchi, but the baechu (hangul: 배추; Napa cabbage) used for kimchi is replaced with Korean radish (called "mu", 무 in Korean).  "Kkakdugi" is a popular banchan (side dish) enjoyed by Koreans and others.

Texas Hill Country AVA: The Texas Hill Country AVA is an American Viticultural Area located in the Texas Hill Country north of San Antonio and west of Austin, Texas.  The appellation is the second largest American Viticultural Area behind the Upper Mississippi River Valley AVA and covers an area of over 9000000 acre .  Established in 1991, it is the southernmost AVA.  Despite the cultural influence of the local Texas German population, most of the grape varietals grown in the Texas Hill Country originate from France, Italy, or Spain rather than the cooler climate of Germany.

Human trafficking in Belgium: Belgium is a source, destination, and transit country for men, women, and children subjected to trafficking in persons, specifically forced labor and forced prostitution.  Victims originate in Eastern Europe, Africa, East Asia, as well as Brazil and India.  Some victims are smuggled through Belgium to other European countries, where they are subjected to forced labor and forced prostitution.  Male victims are subjected to forced labor and exploitation in restaurants, bars, sweatshops, horticulture sites, fruit farms, construction sites, and retail shops.  There were reportedly seven Belgian women subjected to forced prostitution in Luxembourg in 2009.  According to a 2009 ECPAT Report, the majority of girls and children subjected to forced prostitution in Belgium originate from Eastern Europe and Nigeria; some young foreign boys are exploited in prostitution in major cities in the country.  Local observers also report that a large portion of children trafficked in Belgium are unaccompanied, vulnerable asylum seekers and refugees.  According to the Belgian immigration office, the government identified eight children between January and June 2009 as trafficked.  Foreign workers continued to be subjected to involuntary domestic servitude in Belgium, some involving members of the international diplomatic community posted in Belgium.

Human trafficking in the Republic of the Congo: The Republic of the Congo (ROC) is a destination and transit country for children subjected to trafficking in persons for the purposes of forced labor and forced prostitution.  Most sources agree that up to 80 percent of all trafficked children originate from Benin, with girls comprising 90 percent of that group.  Togo, Mali, Guinea, Cameroon, the Democratic Republic of the Congo, and Senegal are also sources of victims found in the Congolese republic.  Internally trafficked children represent 10 percent of all child victims, the majority of which originate from the Pool region.  Many child victims are subjected to forced labor, including in domestic work, market vending and fishing; girls are also exploited in the sex trade.  Child victims generally experience harsh treatment, long work hours, and almost no access to education or health services; they receive little or no remuneration for their work.  Other village children, however, live voluntarily with extended relatives in cities, attend school, and do housework in exchange for food, in a traditional cultural and familial pattern that does not entail abuse.
