Party generally support the spirit of the 1992 Consensus, where the KMT claimed that there is one China, but that the ROC and PRC have different interpretations of what "China" means. They favour eventual unification with China. Regarding independence, the mainstream Pan-Blue position is to maintain the status quo, while refusing immediate unification. President Ma Ying-jeou stated that there will be no unification nor declaration of independence during his presidency. Some Pan-Blue members seek to improve relationships with PRC, with a focus on improving economic ties. National identity Roughly 84 per cent of Taiwan's population are descendants of Han Chinese immigrants from Qing China between 1683 and 1895. Another significant fraction descends from Han Chinese who immigrated from mainland China in the late 1940s and early 1950s. The shared cultural origin combined with several hundred years of geographical separation, some hundred years of political separation and foreign influences, as well as hostility between the rival ROC and PRC have resulted in national identity being a contentious issue with political overtones. Since democratic reforms and the lifting of martial law, a distinct Taiwanese identity (as opposed to Taiwanese identity as a subset of a Chinese identity) is often at the heart of political debates. Its acceptance makes the island distinct from mainland China, and therefore may be seen as a step towards forming a consensus for de jure Taiwan independence. The Pan-Green camp supports a predominantly Taiwanese identity (although "Chinese" may be viewed as cultural heritage), while the Pan-Blue camp supports a predominantly Chinese identity (with "Taiwanese" as a regional/diasporic Chinese identity). The KMT has downplayed this stance in the recent years and now supports a Taiwanese identity as part of a Chinese identity. In annual polls conducted by National Chengchi University, Taiwanese identification has increased substantially since the early 1990s, while Chinese identification has fallen to a low level, and identification as both has also seen a reduction. In 1992, 17.6 percent of respondents identified as Taiwanese, 25.5 percent as Chinese, 46.4 percent as both, and 10.5 percent non-response. In June 2021, 63.3 percent identified as Taiwanese, 2.6 percent as Chinese, 31.4 percent as both, and 2.7 percent non-response. A survey conducted in Taiwan by Global Views Survey Research Center in July 2009 showed that 82.8 percent of respondents consider the ROC and the PRC as two separate countries with each developing on its own but 80.2 percent think they
