签订 (qiān dìng): Thỏa thuận và ký kết (một hiệp ước, vv)

After several rounds of negotiations, the two sides finally reached an agreement on the terms of cooperation and formally signed a three-year contract last Friday.

The leaders of the two countries signed a new trade agreement this morning at the Great Hall of the People, which will help promote bilateral economic development.

Witnessed by a lawyer, Mr. Zhang and Ms. Li signed a house rental contract, agreeing to move into the new residence early next month.

The company requires all new employees to sign a confidentiality agreement on their first day, promising not to disclose any trade secrets.

Because the two parties still disagree on the payment method, this purchase contract has not yet been signed, and the project progress has been affected as a result.
