Hau spoke at Taipei City Hall shortly after the 2013 Guang Da Xing No. 28 incident involving Taiwan and the Philippines occurred on 9 May 2013 in disputed water of the South China Sea. In his comments, Hau urged the ROC government to take action against the Philippine government by suspending all exchanges with them, banning the recruitment of their workers, sending naval ships and extending their patrol beyond the exclusive economic zone to protect Taiwanese fishermen, retracting the 2013 Dragon Boat Festival invitation extended to the Philippines, (an event scheduled to take place in June), bringing the killers to justice, compensating the family of the shooting victim, and suspending the donation of two ROC ambulances to the Philippines. He also advised Taipei residents not to travel to the Philippines.[7][8]

In early July 2013, Hau led a delegation to attend the Shanghai-Taipei City Forum in Shanghai. He met with the Director of Taiwan Affairs Office Zhang Zhijun and Mayor of Shanghai Yang Xiong. The Taipei City Government and Shanghai City Government will sign several memorandums regarding libraries, district administration and "1999" city hotline service. The delegation also will discuss about cross-strait business, sports, education and media.

During his stay in Shanghai, he made a statement regarding the recently signed Cross-Strait Service Trade Agreement between Straits Exchange Foundation and Association for Relations Across the Taiwan Straits that China should establish mutual trust with Taiwan, reassure the Taiwanese people and strive for Taiwanese support on the issue.[9]

Hau declared his candidacy for the Keelung City legislative seat in July 2015.[12][13] However, he lost to Democratic Progressive Party candidate Tsai Shih-ying.[14] Hau announced his intention to run for the position of Kuomintang chair on 21 January 2016, shortly after former party leader Eric Chu had resigned the position following defeat in the presidential elections.[15] Hau dropped out of the chairmanship election a few days later.[16] He was reappointed a vice chairman of the Kuomintang in May 2016.[17]

On 7 January 2017, he joined the KMT chairmanship election.[18][19] The vote was held on 20 May 2017. He finished third in a field of six candidates.
