A seal, in an East Asian context, is a general name for printing stamps and impressions thereof which are used in lieu of signatures in personal documents, office paperwork, contracts, art, or any item requiring acknowledgement or authorship.
 China, Japan, Taiwan, and Korea currently use a mixture of seals and hand signatures, and increasingly, electronic signatures.
 It is used to a lesser extent in Vietnam by authorised organisations and businesses, and also traditional Vietnamese artists.
 It was more common in Vietnam prior to French rule, when thereafter the practice of signature became a commonality, although western-like signatures are usually seen as having less authority in a company situation.
The Weatherhead East Asian Institute (WEAI) at Columbia University is a community of scholars affiliated with Columbia's schools, bringing together over 50 full-time faculty, a diverse group of visiting scholars and professionals, and students from the United States and abroad.
 Its mission is to train new generations of experts on East Asian topics in the humanities, social sciences, and the professions and to enhance understanding of East Asia in the wider community.
 Since its establishment in 1949 as the East Asian Institute, the WEAI has been the center for modern and contemporary East Asia research, studies, and publication at Columbia, covering China, Japan, Taiwan, Hong Kong, Korea, Mongolia (Inner Asia), Tibet, and, increasingly, the countries of Southeast Asia.
Stereotypes of East Asians are ethnic stereotypes found in U.S. society about first-generation immigrants, and American-born citizens whose family members immigrated to the U.S., from East Asian countries, such as China, Japan, South Korea, and Taiwan.
 Stereotypes of East Asians, like other ethnic stereotypes, are often portrayed in the popular press, literature, film, and other creative expressions.
 These stereotypes have been largely and collectively internalized by society and have mainly negative repercussions for Americans of East Asian descent and East Asian immigrants in daily interactions, current events, and governmental legislation.
 Media portrayals of East Asians often reflect an Americentric perception rather than realistic and authentic depictions of true cultures, customs and behaviors.
 East Asians have experienced discrimination and have been victims of hate crimes related to their ethnic stereotypes, as it has been used to reinforce xenophobic sentiments.
Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae.
 They are native to Japan, Korea, China, Bhutan, and Burma.
 (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Pseudocydonia sinensis, the Chinese quince, is a deciduous or semi-evergreen tree in the family Rosaceae, native to eastern Asia in China, and the sole species in the genus Pseudocydonia.
 It is closely related to the east Asian genus "Chaenomeles", and is sometimes placed in "Chaenomeles" as "C. sinensis", but notable differences are the lack of thorns, and that the flowers are produced singly, not in clusters.
 The Chinese quince is also closely related to the European Quince genus "Cydonia"; notable differences include the serrated leaves, and lack of fuzz.
The East Asian people are indigenous to East Asia, which consists of Mainland China, Hong Kong, Macau, Japan, Taiwan, Mongolia, North Korea and South Korea, and for some authors, Vietnam, due to significant influence of East Asian cultural sphere on the Vietnamese culture.
 Major ethnic groups of East Asia are: Han, Japanese, and Koreans.
 Other ethnic groups of East Asia include: Manchus, Tibetans, Mongols, Uyghurs, Kazakh, Kyrgyz and Ryukyuan.
 However, Uyghur, Kazakh and Kyrgyz peoples who live in East Asia are not considered East Asians but Central Asian and are of mixed Mongoloid and Caucasoid origin.
 Indigenous people of Northeast Asia such as Buryats, Evenks, and Yakuts are geographically and racially East Asian but due to the national and political dividing lines, East Asians north of China and Mongolia are not politically East Asian.
EAFF E-1 Football Championship, known as the East Asian Football Championship from 2003 to 2010, and the EAFF East Asian Cup for the 2013 and 2015 editions, is a men's international football competition in East Asia for member nations of the East Asian Football Federation (EAFF).
 Before the EAFF was founded in 2002, the Dynasty Cup was held between the East Asian top four teams, and was regarded as the unofficial East Asian Championship.
 There is a separate competition for both men (first held in 2003) and women (first held in 2005).
 There was also a combined points competition in 2005, where the results of the men's and women's teams are added together (not including qualifiers).
Asian Brazilians are Brazilian citizens of full or predominantly East Asian, South Asian and in some cases South East Asian ancestry, or an Asian-born person permanently residing in Brazil.
 Asian Brazilian community received most of immigrants from the East Asian region, although there have also been smaller numbers of South Asians, from the Indian sub-continent, as well as from the Caribbean, Mozambique, and Kenya.
 The 2011 estimate for Brazilian ciganos is about 800,000, but they are not counted as Asian, although they have ancestors coming from South-Asia.
 People of West-Asian (including Jewish) origin generally do not self-identify as Asian in Brazil as their phenotype since Greco-Roman and Persian conquest has an overlapping with Greece and Iran.
 On the other hand in some states like Amapa, the Amerindian and East-Asian population are put in one category.
 Based on these figures the percentage Asian-Brazilians would break down as follows: East-Asian or Amerindian 3%, West-Asian 1% and South-Asian or gypsy 1%.
East Asian studies is a distinct multidisciplinary field of scholarly enquiry and education that promotes a broad humanistic understanding of East Asia past and present.
 The field includes the study of the region's culture, written language, history, and political institutions.
 East Asian Studies is located within the broader field of Area studies and is also interdisciplinary in character, incorporating elements of the social sciences (anthropology, economics, sociology, politics etc.) and humanities (literature, history, art, film, music, etc.), among others.
 The field encourages scholars from diverse disciplines to exchanges ideas on scholarship as it relates to the East Asian experience and the experience of East Asia in the world.
 In addition, the field encourages scholars to educate others to have a deeper understanding of, and appreciation and respect for, all that is East Asia and, therefore, to promote peaceful human integration worldwide.
