query: What is the proposed legislation by South Korean lawmakers regarding the Gando Convention?
answer: In 2004, 59 South Korean lawmakers proposed legislation that would declare the Gando Convention, signed under Japanese rule, "null and void".  This was in response to China's claims regarding Balhae and Koguryo.  Later that year, South Korea and China reached an understanding to refrain from further involvement in the historical controversy.
