Anti-China demonstrators staged a protest against Chinese envoy Chen Yunlin on Wednesday as he toured Taiwan capital Taipei on the final day of a three-day visit.
The group was waiting for Chen as he arrived at an international flower expo in the city.
"A nobody from China, and flower expo becomes his private garden," a lone protester shouted, honking an airhorn. "Taiwan has no dignity."
Chen and his Taiwanese counterpart Chiang Pin-kung on Tuesday held talks and signed an agreement on medical cooperation.
"Regular talks between the two sides guarantee peace and prosperity in the Taiwan Strait and the region," Taiwan's chief delegate Chiang said at the start of the meeting at one of the city's main hotels.
Sitting across from Chiang was China's Chen, who arrived on Monday for what appears to have become a traditional year-end trip to the island.
Both negotiators represent quasi-official bodies in charge of direct contacts since the two sides have no formal relations.
"I believe more and more Taiwan people will support negotiations between our two associations," Chen said.
Several times during the day Chen was met with small-scale protests, highlighting the fact that the warming of ties is far from universally welcomed on the island of 23 million.
Anti-China protesters had vowed to follow Chen "every step of the way" during his three-day visit to the island, and about 10 gathered outside the hotel Tuesday.
Police, citing the need to allow the hotel to operate normally, in the end linked hands and circled the group of protesters, taking them to a waiting van amid minor scuffling.
Later in the day, members of the Falungong spiritual movement, which is banned in China, staged a protest near another venue where Chen met the top Taiwan official in charge of mainland policy Lai Shin-yuan.
The atmosphere at the closed-door meeting was "friendly and candid", Lai said afterwards, but added that she had conveyed concerns held by many Taiwanese people about the perceived military threat from China.
It is estimated that the People's Liberation Army has more than 1,600 missiles aimed at the island.
At the negotiation table, the two delegations discussed the need for a future agreement on investment protection.
Zheng Lizhong, a member of the Chinese delegation, said they had made progress on the issue and would sign an agreement soon.
Taiwan has been a major investor in China in recent years, providing more than 100 billion US dollars in financing, according to some estimates, as well as crucial technological know-how.
Tuesday's talks also covered epidemic-control measures and joint research and development of medicines, Taiwanese officials said.
At the end of the discussions, the two sides signed an agreement on cooperation in the health field, which has become an area of increased importance given more frequent interaction.
Taiwan and China have been governed separately since the end of a civil war in 1949, but Beijing still considers the island part of its territory and has vowed to bring about reunification even if it means war.
Despite this underlying tension, and a continued Chinese military build-up, the two sides have seen significant progress since 2008 after the election in Taiwan of the China-friendly politician Ma Ying-jeou as president.
Ma has pursued a programme of steadily increasing economic ties, culminating with the signing in June of a sweeping framework agreement for trade.
Ma's administration has also actively promoted tourism between the two sides, partly to boost economic exchanges, and partly in hopes of fostering goodwill at the people-to-people level.
Both sides agreed Tuesday to increase the daily quota of Chinese visitors from 3,000 to 4,000 from January 1 to "boost the tourism effect" and allow individual Chinese tourists to visit Taiwan next year.
Chen is scheduled to depart for China at 0450 GMT.
