"The government has approved exporting those core LCD technologies to China, considering the need to manage the fast-growing Chinese market locally and economic cooperation between South Korea and China," the prime minister's office announced in a statement.

Many tech companies rely on China for cheap labor, custom tax exemptions, and large manufacturing facilities.  The United States, Canada, England, and numerous other countries call upon Chinese-made products sold to consumers, but several companies have been criticized -- and sometimes punished -- by host governments.  South Korean and Japanese companies, for example, often undergo strong public scrutiny when they attempt to offshore manufacturing processes.

The Samsung Chinese plant is expected to open in 2012, and will manufacture 60,000 glass substrates per month.  LG's facility is expected to manufacture up to 120,000 glass substrates per month once the plant opens during Q1 or Q2 next year.

In exchange, either the companies or the Chinese government will pay South Korea a portion of the revenue generated by the tech companies' manufacturing plants in China.

AU Optronics, an LCD company based in Taiwan, also is pleading with its government to adjust its cross-straight investment agreement with China so it can build LCD plants outside of Taiwan.  A growing number of tech companies based in Taiwan have asked the country's Economic Minister to ease legislation so they have the ability to more easily move factories outside the country.
