Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Products (Product_ID VARCHAR, Product_price INTEGER)
TABLE: CREATE TABLE ORDER_ITEMS (Order_ID VARCHAR, Product_ID VARCHAR)
TABLE: CREATE TABLE Customer_Orders (Order_Date VARCHAR, Order_ID VARCHAR)

### Question ###
What are the order dates of orders with price higher than 1000?

### Accurate SQL ###

SELECT T1.Order_Date FROM Customer_Orders AS T1 JOIN ORDER_ITEMS AS T2 ON T1.Order_ID = T2.Order_ID JOIN Products AS T3 ON T2.Product_ID = T3.Product_ID WHERE T3.Product_price > 1000
