China recognizes Taiwan as an independent country in essence and it's non sense for Chinese unifying Taiwan

China bans Taiwan websites ending with .tw. I have tried to visit Taiwan websites from China. China bans free exchange of Chinese Yuan with Taiwan dollars. China regards those living or companies in Taiwan as non-residents for tax purposes. China uses different characters from Taiwanese in spite of some Taiwanese words being used for writing checks or bills of exchange. China blocks US PCAOB's access of audit documentation related to US listed companies with operation in China. Taiwan doesn't block US PCAOB's access of audit documentation related to US listed companies with operation in China, Hong Kong and Taiwan. 

Listed companies on Chinese stock exchange doesn't adopt International Financial Reporting Standards (IFRS). Listed companies on Taipei Exchange adopt IFRS (translated from English after alternatives reduction). In the Chinese Accounting Standards for Business Enterprises, said by China in convergent with IFRS, China intentionally didn't define enterprises under common control of state as not related parties and classified land use rights as intangibles rather right of use assets under the cirumstances that there are tremendous land use rights transactions for free or low cost and subsidies between state and state-owned entities and there are tremendous loan, mergers and acquisitions and underwriting transactions among state-owned entities. State owned financial institutions in China never disclosed themselves as related parties to the issuers when they underwrote or sold securities of other state-owned enterprises.

 China violates Constitution of Republic of China effective since 1947.

Taiwan follows Constitution of Taiwan effective since 1947 followed by modification made afterwards.

China recognizes Taiwan as an independent country in essence. 

Chinese military operation against Taiwan is aggression.

Considering that China neglected UN resolution on ceasing aggression in Korea in 1951, it's necessary for the International Community to take preemptive action against China to stop aggression or hold Chinese accountable to aggression in Korea for violating UN Resolution immediately.
