My comment:
(a) 南京条约 Treaty of Nanking
http://en.wikipedia.org/wiki/Treaty_of_Nanking
(signed in 1842 to mark the end of the First Opium War (1839–42))
(b) 北京条约
Convention of Peking
http://en.wikipedia.org/wiki/Convention_of_Peking
(or the First Convention of Peking; following the Second Opium War; signed
in 1860; ceded Kowloon--and Outer Manchuria, "Although Russia had not been a
belligerent")
(c) 辛丑条约
Boxer Protocol
http://en.wikipedia.org/wiki/Boxer_Protocol
(signed in 1901, after Eight-Nation Alliance's intervention to put down the
Boxer Uprising)
(d) Treaty of Shimonoseki
http://en.wikipedia.org/wiki/Treaty_of_Shimonoseki
(Japanese: 下関条約, traditional Chinese: 馬關條約; signed in 1895)
(f) 火漆(印章)
seal (emblem)
http://en.wikipedia.org/wiki/Seal_(emblem)
(In ancient Mesopotamia seals were engraved on cylinders, which could be
rolled to create an impression on clay)
(h) Only Chinese and Korean languages have the term 不平等条约, a concept
not found in international law. Do not sign it if one does not like the
terms of a treaty--the principle applies to both an individual and a nation.
"A treaty may also be known as: (international) agreement, protocol,
covenant, convention, exchange of letters, etc. Regardless of the
terminology, all of these international agreements under international law
are equally treaties and the rules are the same.
