In 1987, the government of the Republic of China (ROC) open up family visits with the People's Republic of China (PRC), this was the result of mutual interaction over ten years which still can't reconcile the differences between the two sides. The PRC still uses diplomacy to frustrate Taiwan and refuses to renounce the use of force against Taiwan. It is not easy to see any mitigation of the two sides military tension. The PRC points out that they want to solve the issue again and again. But so far, the PRC hasn't bring out any practical plan. If the two sides can use “confidence building measures” to face the topic of the opposite status between China and Taiwan, it only can avoid the different option of “One China” problem between two sides. It also can promote the mutual interaction between two sides. It will not cause war by miscarriage of justice for a short will. However, how to overcome and to show Taiwan's encouraging response to PRC's attitude of open the military information and One China principle. The misgiving of Taiwanese independence and arms race both will be faced while talking about “promoting confidence building measures” between the two sides.
