Siwoo Law Firm has expanded its on-the-ground legal cooperation network in China by signing a strategic memorandum of understanding with TIANNI Law Firm, based in Nanjing, Jiangsu province.

Siwoo said it signed the MOU on the 20th at its Seoul office in Seocho-dong. Attorney Ryu Seung-ho of Siwoo and Managing Attorney Zhang Zhihua of Tianni attended the ceremony and signed the agreement.

Ryu oversees international work at Siwoo and handles legal matters involving greater China. Zhang serves as chair of the Duty Crime Prevention and Defense Committee of the Jiangsu Lawyers Association, Siwoo said.

Siwoo has built working relationships with law firms in major Chinese cities including Beijing, Shanghai, Guangzhou and Xi’an. After forming a partnership last year with Shandong Zhongsheng Chengtai Law Firm, Siwoo said the addition of Jiangsu Tianni as an official MOU partner further broadens its base in China.

Tianni, founded in 2019, operates its headquarters in Nanjing and branch offices in Taizhou in Jiangsu and in Yadong, Yadong County, in Rikaze, Tibet, Siwoo said. Taizhou is considered a manufacturing hub in the Yangtze River basin, while Yadong is a border trade port near India and Bhutan. Siwoo said the footprint gives it a local partner base to respond to legal demand tied to the East China economic region as well as transactions linked to South Asia.

Tianni works in civil and commercial matters, international trade, corporate legal services and intellectual property, and has experience handling cross-border cases, Siwoo said. Practical cooperation with Siwoo will be led by Tianni partner attorney Luo Wei, who specializes in civil-commercial and cross-border matters.

Under the agreement, the firms will cooperate on advisory work for Korean and Chinese companies entering each other’s markets and making investments, international trade and commercial disputes, intellectual property protection, company formation and tax-related advice. When legal needs arise involving either country, they plan to set up a priority referral and engagement system and, depending on the case, form joint response teams to provide integrated legal services.

The firms also agreed to share client and network resources and to strengthen competitiveness in the global legal services market through joint marketing and information exchanges.

Siwoo said it is expanding cross-border legal services in Vietnam, China, Japan and North America through a group structure in which specialists in corporate legal affairs, tax and accounting, and family and inheritance work together.

“This agreement will serve as a foundation to support clients’ overseas expansion and investment risks in a more systematic way through cooperation with a capable local law firm in China,” Ryu said. “We will continue to expand global partnerships and provide integrated, client-centered legal services.”

The two firms said they plan to use the MOU to build a long-term, stable cooperative relationship and support clients’ global activities across a range of Korea-China business areas.
