This characterset was published on March 17, 2000 by the Ministry of Information Industry (zhōnghuárénmíngònghéguó xìnxí chǎnyèbù) under the name Information technology - Chinese Ideograms coded characterset for information interchange - Extension for the basic set (资讯技术 - 资讯交换用汉字编码字元集 - 基本集的扩充 xìnxíjìshù - xìnxíjiāohuàn yòng hànzì biānmǎ zìfújí - jīběnjí de kuòchōng).
The purpose of this characterset is to combine Unihan Extention A with the previous GB charactersets but also to create enough codepoints for Unicode BMP. To realise this a part of the characters are encoded using one byte (0x00 to 0x7F), a part is encoded using two bytes (0x81 to 0xFE for the first byte and 0x40 to 0x7FE for the second byte), and a part is encoded using 4 bytes (0x81308130 to 0xFE39FE30 or otherwise put 0x8130 to 0xFE39 for the first two bytes and 0x8130 to 0xFE39 for the last two bytes).

The Chinese government mandates that all new applications and operating systems sold in China support the GB18030 character set.
