[REEs] Countries lead in high-purity rare earth metal production and refining.

China’s new export licensing rules for rare earths triggers me to understand which countries are the top producers and have the refining technology. 

China, the United States, Myanmar, and Australia are among the top producers of rare earth metals, with China leading in both production volume and refining technology for high-purity output.

Top Producers of Rare Earth Metals

These countries dominate global production and reserves:

Country2024 Production (Metric Tons)Known Reserves (Metric Tons)Refining Capability
China~210,000270,000Advanced
United States~43,00045,000Growing
Myanmar~38,00031,000Limited
Australia~20,00013,000Strong
Thailand~8,00013,000Developing
Russia~2,5002,500Emerging
India~2,9002,900Developing

High-Purity Refining Technology

Producing high-purity rare earths requires advanced separation and purification processes. Here's where the technology stands:

  • China: Dominates the refining stage, controlling over 85% of global rare earth processing. It has the most advanced infrastructure for separating individual rare earth elements.

  • United States: Increasing investment in domestic refining, especially at facilities like Mountain Pass in California, but still relies on China for some processing.

  • Australia: Home to Lynas Rare Earths, the only major non-Chinese company with significant refining capabilities.

  • Japan and South Korea: While not major producers, they have advanced technologies for refining and recycling rare metals, especially for electronics and batteries.

China, the United States, Australia, and Brazil lead in high-purity rare earth metal production and refining, while countries like Turkey, Myanmar, and Pakistan are emerging players with significant reserves but limited refining capacity.

Here’s a comprehensive overview of the global landscape:

[Culture] 解釋希臘藝術的特徵 Properties of Greek Art Explained

希臘藝術由公元前8世紀至希臘化時期,以其對和諧、比例和理想美的強調而聞名。它經歷了明確的階段——幾何、古風、古典和希臘化——每個階段都以日益增長的現實主義和精緻度為特徵。希臘藝術家精通雕塑、陶藝、建築和繪畫,經常描繪神祇、運動員和神話場景,重點在於人體解剖和動作。多利克、愛奧尼克和科林斯式的建築創新反映了他們對平衡和宏偉的追求。希臘藝術受到早期文明的深刻影響,並且後來啟發了羅馬和文藝復興藝術,仍然是西方美學理想的基石。

希臘和意大利藝術有著深厚的歷史聯繫,但在風格、目的和文化強調上卻有所不同。希臘藝術,特別是古典時期的作品,專注於理想化的人體形態、平衡和動態,經常以解剖精確度和男性活力描繪神祇和神話主題。意大利藝術,尤其是在文藝復興時期,深受希臘模型的影響,但注入了情感的深度、宗教象徵以及更具女性美的審美。文藝復興藝術家如米開朗基羅採用了希臘技術,如對比姿勢,但常常誇大比例以增強戲劇效果。希臘藝術讚美神聖的完美,而意大利藝術則擁抱人類的經歷——將現實主義、靈性和創新融合成一種豐富的表現傳統。

Greek art, spanning from the 8th century BC to the Hellenistic period, is renowned for its emphasis on harmony, proportion, and idealized beauty. It evolved through distinct phases—Geometric, Archaic, Classical, and Hellenistic—each marked by increasing realism and sophistication. Greek artists mastered sculpture, pottery, architecture, and painting, often depicting gods, athletes, and mythological scenes with a focus on human anatomy and movement. Architectural innovations like the Doric, Ionic, and Corinthian orders reflected their pursuit of balance and grandeur. Deeply influenced by earlier civilizations and later inspiring Roman and Renaissance art, Greek art remains a cornerstone of Western aesthetic ideals

Greek and Italian art share a profound historical connection, yet they diverge in style, purpose, and cultural emphasis. Greek art, especially from the Classical period, focused on idealized human forms, balance, and movement, often portraying gods and mythological themes with anatomical precision and masculine vigor. Italian art, particularly during the Renaissance, drew heavily from Greek models but infused them with emotional depth, religious symbolism, and a more feminine aesthetic. Renaissance artists like Michelangelo adopted Greek techniques such as contrapposto but often exaggerated proportions for dramatic effect. While Greek art celebrated divine perfection, Italian art embraced human experience—blending realism, spirituality, and innovation into a richly expressive tradition.

[Culture] 人權運動先驅及全球發展 Pioneers and Global Development of the Human Rights Movement

全球人權運動的根源可以追溯到古代的一些聲明,如古列王的圓筒和大憲章,通過啟蒙運動的自由擁護者,以及奪取奴隸制的運動,為道德奠定基礎。在20世紀,戰爭的暴行促使了聯合國的成立和《世界人權宣言》的制定,埃莉諾·羅斯福負責起草。美國的民權象徵,如馬丁·路德·金,羅莎·帕克斯和薛德·馬歇爾推動了美國的倡導,並與去殖民化、赫爾辛基協議及冷戰後外交等全球努力相結合。今天,這場運動擁抱數字權利、氣候正義和包容性,擴大其對全球尊嚴和平等的願景。

The global human rights movement traces its roots from ancient declarations like Cyrus the Great’s Cylinder and the Magna Carta, through the Enlightenment's champions of liberty, and abolitionist movements that laid ethical groundwork. In the 20th century, atrocities of war spurred the creation of the United Nations and the Universal Declaration of Human Rights, with Eleanor Roosevelt leading its drafting. Civil rights icons like Martin Luther King Jr., Rosa Parks, and Thurgood Marshall drove U.S. advocacy, joined by global efforts like decolonization, the Helsinki Accords, and post–Cold War diplomacy. Today, the movement embraces digital rights, climate justice, and inclusion—expanding its vision for dignity and equality worldwide.

Global Development of the Human Rights Movement

Ancient to Early Modern Foundations
539 BCE – Cyrus the Great Issued the Cyrus Cylinder, considered the first charter of human rights.

1215 – Magna Carta (England) Established rule of law and limited monarchial power; early step toward legal rights.

17th–18th Century – Enlightenment Thinkers Philosophers like Locke and Rousseau promoted natural rights and liberty.

19th–Early 20th Century
Abolitionist Movements Anti-slavery campaigns in the U.S. and UK laid groundwork for rights-based activism.

1899 – Hague Convention Early international recognition of rights beyond state control.

1904 – Congo Reform Association Used photography to expose colonial atrocities; early global human rights advocacy.

Post–World War II Era
1945 – United Nations Founded Human rights enshrined in the UN Charter after global outcry over the Holocaust.

1948 – Universal Declaration of Human Rights (UDHR) Drafted with major input from Eleanor Roosevelt; cornerstone of modern human rights law.

1960s–1980s
Civil Rights Movement (U.S.) Shift from civil rights to broader human rights, including economic justice and global solidarity.

Decolonization Movements Newly independent nations pushed for global equity and anti-racism at the UN.

1975 – Helsinki Accords Linked human rights to Cold War diplomacy; gave rise to Eastern Bloc dissident movements.

1990s–Present
Post–Cold War Expansion Human rights became central to global diplomacy, humanitarian intervention, and international law.

Digital Age & Climate Justice New frontiers include data privacy, LGBTQ+ rights, and environmental justice as human rights issues.


Pioneers of the Human Rights Movement in the U.S.

Martin Luther King Jr. Led the Civil Rights Movement using nonviolent resistance; pivotal in the Montgomery Bus Boycott and March on Washington. 

Rosa Parks Sparked the Montgomery Bus Boycott by refusing to give up her bus seat; symbol of quiet defiance. 

John Lewis Organizer of Freedom Rides and Selma marches; long-serving Congressman and advocate for voting rights. 

Thurgood Marshall First Black Supreme Court Justice; won Brown v. Board of Education, ending school segregation. Ella Baker Behind-the-scenes strategist; helped found the SNCC and emphasized grassroots organizing. 

A. Philip Randolph Labor leader and civil rights activist; organized the Brotherhood of Sleeping Car Porters and the 1963 March on Washington. 

James Farmer Co-founder of CORE; led Freedom Rides to challenge segregation in interstate travel. 

Malcolm X Advocated for Black empowerment and human rights; shifted focus from civil rights to global human rights.


Eleanor Roosevelt didn’t just participate — she helped define the modern human rights movement.

Chair of the UN Human Rights Commission (1946–1948) Appointed by President Truman, she led the drafting of the Universal Declaration of Human Rights (UDHR), a foundational document adopted by the United Nations in 19482.

Architect of the UDHR She insisted the Declaration be written in clear, accessible language so it could resonate with people worldwide. Her advocacy helped expand its scope to include not just civil and political rights, but also economic, social, and cultural rights.

Moral Leadership In her famous 1948 speech at the Sorbonne in Paris, she called the UDHR “the international Magna Carta for all men everywhere,” emphasizing its potential to prevent future wars by promoting dignity and justice.

Continued Advocacy Even after her UN tenure, she remained a vocal supporter of civil rights, racial equality, refugee aid, and women's empowerment. Martin Luther King Jr. praised her as “perhaps the greatest woman of our time” for her courage and principle.
